Patch 1.9.20 isn't a routine balance update. It nerfs three dominant mages into irrelevance, buffs several underplayed heroes into viability, and drops a brand-new support on March 11, 2026 — all within MSC 2026 qualifying windows. Your Diamond decisions right now determine whether you're ahead of the meta or chasing it.
The seven heroes worth buying: Gloo, Sora, Helcurt, Yi Sun-Shin, Lukas, Aurora, and Marcel. Here's exactly why, what each costs, and who to prioritize first.
Why Patch 1.9.20 Is a Turning Point
The Mage Meta Just Collapsed
Three nerfs define this patch:
Kagura: Ultimate magic power scaling 105% → 90%, base damage ratio 70% → 60%, skill damage 170% → 155%. Her burst ceiling is fundamentally lower — not slightly adjusted.
Edith: Total Magic Power Bonus 30% → 20%, bonus damage weakened at every hero level. Her hybrid damage profile takes a real hit.
Zhuxin: Base mana 1500 → 1200. Early-game aggression directly limited.
The Buff Side Is Surgical
Lukas: Skill 1 max stacks now apply Stun instead of Airborne — bypasses cleanse mechanics that Airborne doesn't. Skill 2 extra damage jumps from 5–30 + 20% to 40 + 25% Total Physical Attack. Flash Strike scales from 120% to 125%.
Aurora: Skill 1 cooldown at max rank 4s → 3s; Skill 2 9s → 8s. More freeze windows change her entire threat profile.
Saber: Base HP 2400 → 2500, Physical Defense 180 → 200, defense growth 4.1 → 4.5 per level, Skill 1 cooldown halved from 1s to 0.5s. Tankier and faster simultaneously.
Suyou: Hold-cast control upgraded from 0.5s Airborne to 0.6s Stun — uncleansable by certain items. Competitive-level change worth watching.
Eudora: Skill 1 mana cost 65/90 → 60/85. Small, but meaningful for sustained lane pressure.
Why MSC 2026 Makes Now the Right Time
Pro meta and ranked meta have a direct feedback loop. When teams lock in heroes at MSC 2026, those picks flood Mythic queues within 48–72 hours. Players who already own and practice those heroes gain immediate draft leverage.
Community data from MPL PH S16 shows Gloo at 52.71% win rate with a 59.64% ban rate and only 1.13% pick rate. That ban rate tells you everything — teams are afraid of him. Heroes with that profile become first-phase bans at MSC 2026.
Selection Criteria
Win rate above 52% in current ranked data, or confirmed buff trajectory
Ban rate above 40% in Mythic
Role coverage across Tank, Fighter, Assassin (×2), Mage, Support, and flex
MSC 2026 relevance — historical tournament presence or current pro-team priority
Diamond cost-to-value ratio — is Diamonds specifically justified, or can BP substitute?
The 7 Heroes Worth Your Diamonds
Hero #1 — Gloo (Tank/Roamer): Buy First. No Debate.
A 59.64% ban rate combined with a 52.71% win rate means he's simultaneously the most feared and most successful tank in the current meta. When he isn't banned, he wins more than half his games.
Gloo thrives in exactly the direction 1.9.20 pushes — durable frontlines with reliable CC chains over pure burst mages. His split mechanic creates persistent zoning pressure. Paired with Aurora (also buffed this patch), the combo is particularly nasty: freeze targets become perfect Gloo attachment opportunities.
Expect him as a first or second phase ban at MSC 2026. Own him before the tournament starts.
Hero #2 — Yi Sun-Shin (Assassin/Marksman): The Flex That Never Leaves Meta
Yi Sun-Shin hasn't been touched this patch — which, when several alternatives just got nerfed, is effectively a buff by comparison. His dual-role viability in both Jungle and Gold Lane makes him a draft nightmare. The global ultimate gives him map presence that pure assassins lack.
He was S-Tier in the January 2026 jungle meta alongside Helcurt. He's S-Tier now. He'll be in MSC 2026 draft discussions, particularly for teams building jungle-to-global-pressure compositions.
Hero #3 — Helcurt (Assassin): Know His Power Window
Most tier lists won't tell you this: Helcurt's silence is most impactful between minutes 3–8, before enemies complete Purify or build cleanse items. If you're not capitalizing on that window, you're playing him wrong.
In 1.9.20, with the meta shifting toward CC-heavy compositions, his silence becomes more disruptive — he counters the very CC chains that define the current patch. S-Tier in January 2026 jungle rankings, unchanged in 1.9.20.
His ceiling is high. So is his skill floor. This is a Diamond investment for players who commit to mastering him, not a casual pick.
Hero #4 — Sora (Fighter): EXP Lane Bully That Scales
Sora holds S-Tier status in the EXP lane meta, confirmed by January 2026 community data and reinforced by 1.9.20's direction. With Kagura and Edith weakened, teams need fighters who create sustained pressure rather than relying on one-shot windows. Sora fills that gap.
She functions as a secondary frontline in teamfights — absorbs pressure, dishes sustained damage, and scales into a late-game threat tanks can't ignore. Strong in solo queue because she doesn't require coordination to be effective.
Hero #5 — Lukas (Fighter): The Buff That Changes His Ceiling
The key change isn't the damage numbers — it's Stun replacing Airborne on Skill 1 max stacks. Airborne gets countered by certain items. Stun doesn't. At Mythic level, where players build specifically to counter CC, this distinction is the difference between a skill that gets negated and one that always lands.
Correct execution: stack Skill 1 to maximum, then use Flash Strike as a finisher — the enhanced scaling (now 125% Total Physical Attack) makes it a legitimate kill-confirm tool.
Lukas sits A-Tier post-buff. Not yet ban-worthy, which is actually ideal — you'll pick him freely in draft.
Hero #6 — Aurora (Mage): The Indirect Beneficiary
Faster cooldowns on Skill 1 (now 3s at max rank) and Skill 2 (now 8s) mean more CC uptime and more consistent damage. But here's what most guides miss: Aurora benefits indirectly from Kagura and Edith's nerfs. With those two weakened, the midlane opens for alternatives. Her freeze mechanic pairs exceptionally well with the CC-chain emphasis of 1.9.20, and her Gloo synergy creates a two-hero combo that's genuinely difficult to play against.
She's A-Tier, not S-Tier. But in a meta where S-Tier mages just got nerfed, A-Tier with strong synergies is the correct investment.
F2P note: Aurora is obtainable via Battle Points. If your Diamond budget is tight, she's a BP candidate.
Hero #7 — Marcel (Support): The New Hero Timing Window
Marcel launches March 11, 2026 as the 132nd hero. New heroes in MLBB typically have a 2–4 week window where they're either overpowered before nerfs or underexplored — giving you an edge through familiarity alone.
His kit rewards positioning over aggression:
Passive (Platinum Snap): True damage equal to 40% Total Physical Attack + 40% Physical Defense + 40% Magic Defense, then shields Marcel for the same amount. 8s per-target cooldown. Defensive items make him tankier and hit harder simultaneously.
Skill 1 (Framed Moment): 2.5s charge, immobilizes for 1s, deals 400–700 base damage + 50% Total Physical Attack + 100% Physical Defense + 100% Magic Defense.
Ultimate (Golden Hour): 3-second Frozen Moment reducing incoming projectile damage by 50%, freezing minions and jungle objectives, resetting Platinum Snap's cooldown. Game-changing objective control.
The critical insight: his ultimate forces enemies to engage without ranged poke, which inherently favors melee-heavy compositions. Run Gloo + Sora + Marcel and Golden Hour makes your team nearly unkillable during objective fights.
Cost: 599 Diamonds or 32,000 BP. For competitive timing before MSC 2026, Diamonds are the right call — BP grinding takes time you may not have.
Diamond Cost Breakdown
S-Tier heroes with high ban rates justify Diamond spending because their ranked impact is immediate. Marcel justifies Diamonds for the competitive timing window. Lukas and Aurora can wait for BP if your budget is tight.
If you're unlocking multiple heroes before MSC 2026, getting your buy mobile legends diamonds instant delivery sorted early means you're not scrambling during the tournament window when everyone else is topping up simultaneously.
Priority Spending Order
Tier 1 — Buy Immediately (Diamonds)
Gloo → Marcel → Helcurt
Gloo's ban rate means every game you don't own him is a game where you might face him without a counter. Marcel's advantage window closes as the meta adapts. Helcurt's silence window is most impactful right now, before cleanse-heavy builds become standard.
Tier 2 — Strong Investments (Diamonds or BP)
Yi Sun-Shin → Sora
Both S-Tier and worth owning, but their kits are more straightforward to counter than Gloo or Helcurt. Use BP here if you have it stockpiled.
Tier 3 — Situational (BP Preferred)
Lukas → Aurora
Both have legitimate ranked value. Neither demands Diamond spending. Grind BP for both unless you're in a hurry.
Heroes to Avoid Spending Diamonds On
Nerfed Heroes — Wait Two Weeks Minimum
Kagura, Edith, Zhuxin. All three took meaningful nerfs. Kagura's scaling reductions are particularly severe — her burst ceiling is genuinely lower, not slightly adjusted. Edith's Total Magic Power Bonus drop from 30% to 20% weakens her hybrid damage profile significantly. Wait for post-patch win rates to stabilize before considering any of them.
Free BP Alternatives Worth Knowing
Aurora: 32,000 BP — no Diamonds needed
Eudora: BP hero; mana cost buff makes her a legitimate budget mage option
Saber: BP obtainable; HP, defense, and Skill 1 cooldown buffs make him a strong free assassin option
MSC 2026 Meta Predictions
Expected first-phase bans: Gloo (59.64% ban rate in MPL PH S16 already confirms this), Helcurt, Sora
Priority picks if bans miss: Yi Sun-Shin (flex jungle/gold lane), Marcel (new hero advantage), Lukas (Stun upgrade harder to counter at pro level)
Mage slot: With Kagura and Edith nerfed, expect Aurora to see increased pro play. Her freeze mechanic creates setup for the CC-chain compositions that dominate 1.9.20.
The players who invest in meta heroes before MSC — not during or after — are the ones climbing during the tournament window, not scrambling to catch up.
How to Top Up Efficiently
All seven heroes at ~599 Diamonds each totals roughly 4,193 Diamonds. But Aurora, Saber, and Eudora are BP candidates — bringing your actual Diamond requirement down to approximately 2,396 Diamonds for the four highest-priority picks (Gloo, Marcel, Helcurt, Yi Sun-Shin).
Practical advice:
Don't top up in small increments — larger purchases typically offer better per-Diamond value
Check for in-game events before topping up; bonus Diamond windows are predictable around patch releases and major tournaments
Stacking a top-up with a Diamond bonus event can stretch your budget by 20–30%

FAQ
Can I unlock these heroes with BP instead of Diamonds? Most of them, yes. Aurora, Saber, and Eudora are strong BP candidates. For S-Tier heroes like Gloo, Helcurt, Yi Sun-Shin, and Sora, BP works but takes significantly longer. Marcel is 32,000 BP — achievable but slow. Rule of thumb: use Diamonds where timing matters, BP where you can afford to wait.
Will these heroes stay meta after MSC 2026? S-Tier heroes with high ban rates tend to hold across multiple patches unless Moonton specifically targets them. Gloo has maintained top-tier status across several patches already. The safest long-term investments are heroes with mechanically strong kits (Helcurt, Yi Sun-Shin) rather than heroes whose strength depends on stat thresholds that can be adjusted numerically.
I already own some of these — what's next? If you own Gloo and Helcurt, prioritize Marcel for the timing advantage, then Sora if you play EXP lane. Own all four S-Tier picks? Marcel is your next Diamond spend, followed by skins for your most-played heroes.
Is Suyou worth buying in 1.9.20? His buff is competitive-level — Stun replacing Airborne, uncleansable by certain items. But community data hasn't placed him in S or A-Tier yet. Watch his win rate over the next two weeks. If it climbs above 52%, he becomes a legitimate Diamond consideration.
Does Eudora's buff make her worth buying? The mana cost reduction is quality-of-life, not meta-defining. She's a solid budget mage obtainable via BP. Not a Diamond priority, but a competent free option if you need a midlane hero.
How do I evaluate Diamond investment risk across patches? Ask yourself: is this hero strong because of unique mechanics or because of high numbers? Mechanics are safer investments. Gloo's kit is mechanically unique — nerfing him requires changing core design, which Moonton does rarely. Kagura's nerfs were purely numerical. That's why she got hit and he didn't.
Bottom Line
Patch 1.9.20 pushes the meta toward durable frontlines, reliable CC chains, and objective-focused compositions. The seven heroes here each fit that framework across different roles.
Spend Diamonds on Gloo, Marcel, Helcurt, and Yi Sun-Shin immediately. Use BP for Aurora and Saber. Evaluate Lukas based on your role preference. Avoid Kagura, Edith, and Zhuxin until the post-nerf dust settles.
MSC 2026 is the inflection point. Own these heroes before the tournament — not after.
