The seven heroes worth spending Diamonds on before the MPL Season 15 Finals: Marcel, Yi Sun-shin, Gloo, Floryn, Fredrinn, Zhuxin, and Kimmy. This roster covers every critical role in the current meta and reflects actual pro-play priority heading into the March 2026 playoff climax. Team Liquid Philippines' Grand Finals victory over ONIC PH in a brutal BO7 — with Luo Yi as the Game 7 MVP pick by Sanji — confirms exactly which hero archetypes decide championships. Own these before the Finals hype peaks, and you're investing in heroes that stay relevant deep into Ranked Season 40.
Why MPL Season 15 Playoffs Meta Should Drive Your Diamond Spending
Pro-play meta doesn't just reflect what works at the highest level — it shapes what you'll face in ranked within days of a major tournament. Players copy what they see on stream. Ranked Season 40 launched March 3, 2026, with fresh resets for S4/S8/S9 ranks, meaning millions are actively climbing right now and watching what wins at the pro level.
Heroes with high MPL pick/ban rates flood Mythic and Legend lobbies within one to two weeks of playoff broadcasts. Own them before the Finals and you're ahead of the curve. The S1 reset on March 11 creates a second wave of ranked activity — perfectly timed with Marcel's release on the same date.
Selection criteria — three filters applied simultaneously:
Pro-play priority: Consistent presence in MPL S15 playoff drafts as first-picks or priority bans
Solo-queue transferability: Kits that deliver value without perfect team coordination
Diamond cost-to-value ratio: Justified investment through Season 40 and beyond
The 7 Best Heroes to Buy Before MPL Season 15 Finals
1. Marcel — The New Support That Changes Everything
Most urgent purchase on this list. Releasing March 11, 2026 — same day as the S1 ranked reset — this 132nd hero is a Support built around disrupting projectile-heavy compositions in ways the meta hasn't seen before.
His passive, Platinum Snap, deals true damage scaling off 40% total physical attack + 40% physical defense + 40% magic defense, while shielding Marcel for the same amount. That dual-scaling means tanky support builds don't sacrifice damage. Framed Moment (Skill 1) charges over 2.5 seconds and immobilizes targets for 1 second — reliable CC that scales with both attack and defense stats.
The real game-changer: his ultimate Golden Hour creates a 3-second Frozen Moment that reduces incoming projectile damage by 50%, nullifies certain projectiles outright, freezes minions/objectives/turrets, and resets Platinum Snap. In a meta where Kimmy and Wanwan dominate, a support who neutralizes projectile burst mid-teamfight is immediately tier-defining.
Cost: 599 Diamonds or 32,000 BP. BP is viable but takes weeks — if you want Marcel ready for the Finals window, Diamonds are the practical choice.
2. Yi Sun-shin — The Assassin/Marksman Pros Won't Let Go
S-tier consensus across multiple patches. His revamped ultimate reveals all enemies on the map, stuns, and delivers AoE ram damage — a macro tool that wins games at the information level before a single teamfight starts. Skill 1 grants control immunity, making him nearly impossible to lock down during his own engage.
Honest caveat: high skill ceiling. Community testing confirms his kit underperforms in Gold Lane — EXP lane or jungle is where he belongs. Commit to learning optimal positioning and the payoff is a hero MPL teams genuinely fear drafting against.
3. Kimmy — The Gold Lane Carry With Built-In Suppression
Her revamp turned a niche pick into a legitimate S-tier threat. Skill 2 now suppresses targets — hard CC that very few marksmen possess. Skill 1 allows wall-passing, provides movement speed, and fires homing projectiles, giving her escape tools traditional marksmen lack entirely. Her ultimate vacuums enemies into position for follow-up.
She functions in both mid and gold lane, making her a flex pick in draft — exactly what MPL teams want when hiding their win condition. For solo-queue, her self-sufficiency through escapes and CC means she doesn't need a roamer babysitting her all game.
4. Fredrinn — The Unkillable EXP Lane Anchor
The EXP lane pick that punishes every dive composition. His kit taunts enemies into attacking him, converts incoming damage into gray HP (recoverable health), then detonates it with his ultimate combined with Retribution for massive burst. Community consensus: firmly S-tier in both jungle and EXP lane.
The current meta explicitly favors utility junglers enabling assassin EXP laners. Fredrinn IS that assassin EXP laner — he just happens to be unkillable while setting up his burst window. Pairs exceptionally well with utility supports.
5. Zhuxin — The Mid Lane Executioner
Mid-lane dominance through displacement and execution. Skill 1 displaces and throws enemies, disrupting teamfight positioning. Her Sky Piercer ultimate executes low-HP targets — a mechanic that rewards game sense and punishes overextension.
Knowing when to hold Sky Piercer versus burning it immediately is what separates average and strong Zhuxin players. In solo-queue, the execution threshold means she consistently secures kills other mages would miss. S-tier confirmed by community testing, with zone control that forces respect throughout the game.
6. Floryn — The Support That Wins Through Attrition
Simple value proposition, devastating in practice: her ultimate heals all allies globally, regardless of map position. Her Dew passive shields a chosen ally, providing persistent protection that accumulates across an entire match. Viable as roamer, works in both coordinated and solo-queue environments.
This is the support that doesn't require your team to play around her — she plays around them. In a Finals meta decided by sustain and positioning, Floryn's global presence means she's always relevant even when she's physically across the map.
7. Gloo — The Tank That Refuses to Die and Refuses to Leave
His revamp made him one of the most disruptive tanks in the game. The attach mechanic lets him latch onto enemies and share damage taken — punishing enemies for focusing him while protecting his team. His goo creates heals, explosions, and stuns across the map, giving him area denial most tanks can't replicate.
Excels in both EXP lane and roaming, which gives him draft flexibility. Community consensus is unanimous on S-tier. For solo-queue specifically, his ability to create chaos and survive independently makes him forgiving of the coordination gaps inevitable in ranked lobbies.
Diamond Cost Breakdown
Total for all 7: ~4,193 Diamonds. Most active players already own 2–3 of these, bringing realistic spend closer to 1,800–2,400 Diamonds.
If you're planning to buy mobile legends diamonds for new heroes before the Finals, prioritize Marcel first — he's the only hero on this list you definitively cannot own yet, and his release timing with the S1 reset creates an immediate ranked impact window.
BP vs. Diamonds: Every hero here is technically available at 32,000 BP. Grinding that takes roughly 2–3 weeks of consistent daily play. For Marcel specifically, BP grinding means missing the entire early-meta window where his kit is least understood and most exploitable. For heroes you don't urgently need, BP is fine. For Marcel and anything you want immediately, Diamonds are the efficient choice.
Solo-Queue Reality Check
Not every MPL-dominant hero translates cleanly to ranked. The distinction matters before you spend.
Works immediately regardless of team coordination:
Fredrinn — self-contained kit, creates his own damage absorption and burst window
Floryn — global ultimate helps teammates who don't even know she's helping them
Gloo — creates value through chaos, which is abundant in every ranked lobby
Rewards investment and coordination:
Yi Sun-shin — highest execution gap on this list; using his map-wide ultimate optimally requires constant minimap reading. Avoid Gold Lane — a common mistake for players used to marksmen
Marcel — both you and opponents are learning his kit simultaneously; knowing which enemy abilities his ultimate counters takes games to develop
Counter-picks to anticipate:
Quick Build Directions for MPL S15 Meta Heroes
Emblem Priorities
Core Item Priorities
Marcel: Stack physical AND magic defense simultaneously — Oracle and Antique Cuirass are unusually efficient because his passive scales off both
Gloo: Dominance Ice is core; his mark mechanic already reduces healing, stacking this amplifies his anti-sustain role
Fredrinn: Cursed Helmet + Antique Cuirass for gray HP conversion efficiency; Retribution spell is mandatory for his ultimate combo
Floryn: Fleeting Time for ultimate CDR; Courage Mask for roam gold generation
Kimmy: Magic items amplifying Skill 1 homing damage; Genius Wand for magic penetration
Zhuxin: Genius Wand into Divine Glaive for penetration; Clock of Destiny for scaling
Yi Sun-shin: Corrosion Scythe for attack speed synergy; Malefic Roar for late-game physical penetration
Spell notes: Retribution is mandatory for Fredrinn jungle. Flicker suits Gloo's engage patterns. Purify is worth considering on Kimmy and Yi Sun-shin — the current ranked landscape is heavy on CC, and community testing confirms cleanse counters are a defining feature of Season 40 lobbies.
March 2026 Patch Buffs: Three More Heroes Worth Knowing
The March 2026 patch delivered meaningful buffs to Saber, Aurora, and Eudora — not top-7 priority, but relevant if you already own them.
Saber: Base HP increased to 2,500 (from 2,400), physical defense raised to 200 (from 180), defense growth per level improved to 4.5 (from 4.1), Skill 1 cooldown slashed to 0.5 seconds from 1 second. That cooldown reduction is significant for combo execution speed.
Aurora: Skill 1 cooldown now 6s–3s (down from 6s–4s), Skill 2 now 12s–8s (down from 12s–9s) — freeze chains become more consistent in extended fights.
Eudora: Skill 1 mana cost reduced to 60/85 from 65/90 — small individually, but compounds significantly across a full game's worth of poke.
None of these displace the top 7 in meta priority. But if you own them, the patch makes them viable secondary options when your primary picks are banned.
How to Top Up Diamonds Before the Finals
Top up before March 11 — Marcel's release date and the S1 ranked reset. After that, demand spikes as players rush to unlock the new hero and push fresh ranked placements simultaneously.
For players who want to top up mlbb diamonds fast and cheap, BitTopup offers competitive rates with fast delivery — practical when you're working against a specific release date. Calculate your Diamond gap using the table above, add a small buffer for any event bundles dropping during the Finals period, and top up in one transaction.
Covering your hero gaps: roughly 2,400 Diamonds is a single mid-tier top-up. Starting from zero on all 7 heroes, budget approximately 4,200 Diamonds and look for bundle deals that reduce the per-Diamond cost.
Frequently Asked Questions
Can I unlock all 7 heroes with Battle Points instead of Diamonds? Yes — every hero is available at 32,000 BP each. The trade-off is time: 2–3 weeks of daily grinding per hero. Marcel is only available from March 11, so BP grinding starts from zero on that date. For the Finals meta window, Diamonds are the only realistic option for him.
Will these heroes stay meta after the Finals? Almost certainly for most of them. Gloo, Floryn, and Fredrinn have been dominant across multiple patches — their kits are fundamentally strong, not dependent on a specific meta condition. Marcel is the only unknown as a new hero; his power level may be adjusted once Moonton has win-rate data.
Luo Yi won Game 7 of the Grand Finals — should I buy her too? Sanji's Game 7 MVP performance is significant, but one Finals game doesn't make her a must-buy for solo-queue. Her rotation mechanic requires coordination to execute effectively. Worth considering if you enjoy high-skill-ceiling mages, but her solo-queue transferability is lower than the seven heroes listed above.
Are any of these heroes too difficult below Mythic rank? Fredrinn, Gloo, and Floryn are accessible at any rank — forgiving kits that deliver value without advanced mechanics. Yi Sun-shin and Marcel have steeper learning curves. Zhuxin and Kimmy sit in the middle: learnable within 10–15 games, but expect underperformance while developing game sense around their kits.
Does the Ranked Season 40 reset affect which heroes to prioritize? Yes. The S4/S8/S9 resets on March 3 and S1 reset on March 11 put a large portion of the player base in placement matches simultaneously. During placements, tanky heroes (Gloo, Fredrinn) and global-impact supports (Floryn) overperform because they compensate for coordination gaps most pronounced in early-season ranked games. Prioritize those three if you're actively climbing during the reset window.
What's the MPL PH S15 prize pool context? The Grand Finals carried a USD 150,000 prize pool. At that level, every pick and ban reflects weeks of scrim preparation and meta analysis — not experimentation. That's exactly why MPL playoff drafts are the most reliable signal for which heroes are worth your Diamond investment.
