Marvel Rivals Season 10 (Butcher's Blasphemy): start time by region, Gorr the God Butcher, the six-division rank reset, and measured Season 9.5 baselines.
Season 10 (Butcher's Blasphemy) launches September 11, 2026 at 9:00 AM UTC after an estimated 2-hour maintenance. Gorr the God Butcher joins as a new Duelist, competitive ranks drop six divisions (two full tiers), and Scarlet Witch gets a full rework. Batru's Season 10 tier list, counters and ban rates update automatically as ranked matches are recorded — until the sample is large enough, our pages show final Season 9.5 numbers, clearly labeled.
The Season 10 update begins September 11, 2026 at 9:00 AM UTC, with an estimated two-hour server maintenance before play resumes.

Gorr the God Butcher (new Duelist): wields All-Black the Necrosword, converts defeated enemies into Black Berserkers, and his ultimate transforms the sword into the Annihilablade to command every active Berserker at once. He has no match data yet — his tier placement will appear on our tier list once enough Season 10 ranked matches are recorded.
Scarlet Witch rework: the official patch notes confirm a full ability and gameplay rework, including the new Scarlet Hex ability. She ended Season 9.5 at 48.02% win rate (#41 of 55 heroes) — the rework is the single biggest variable in the early Season 10 meta.
New map: God Quarry, a Domination-mode map, arrives September 24 alongside Galacta's Gift Vol. 3. Jeff-themed events (Dream Eater, Superstar Search) start September 18.
Strategist ultimate economy: the patch notes flag a shift in how the entire Strategist roster generates Ultimate Energy — a role-wide change worth watching across every support's win rate.
Ranks drop six divisions — two full tiers — from your final Season 9.5 placement (they can't drop below Bronze III, the lowest rank). End-of-season rewards are based on the peak rank you reached, not where you finished.
| Season 9.5 finish | Season 10 start |
|---|---|
| Bronze or Silver (any division) | Bronze III (floor) |
| Gold III / II / I | Bronze III / II / I |
| Platinum III / II / I | Silver III / II / I |
| Diamond III / II / I | Gold III / II / I |
| Grandmaster III / II / I | Platinum III / II / I |
| Celestial III / II / I | Diamond III / II / I |
Patch notes tell you who changed; they don't tell you the baseline. These are the headline Season 10 balance targets with their final Season 9.5 numbers from 689,871 ranked matches in Batru's data warehouse (snapshot 2026-09-10) — frozen here so you can measure the patch's real effect once Season 10 data lands. The pattern is coherent: the nerfs target the top of the win-rate table, the buffs target heroes sitting just under 50%.
| Hero | S10 change | S9.5 win rate | WR rank | S9.5 ban rate |
|---|---|---|---|---|
| Scarlet Witch | Reworked | 48.02% | #41 | 0.78% |
| Black Cat | Adjusted | 54.38% | #12 | 66.90% |
| Wolverine | Buffed | 49.21% | #34 | 2.01% |
| The Hood | Nerfed | 56.85% | #5 | 16.36% |
| Cloak & Dagger | Nerfed | 49.70% | #30 | 35.34% |
| Mantis | Nerfed | 60.05% | #1 | 6.31% |
| Emma Frost | Buffed | 49.44% | #32 | 3.76% |
| Star Lord | Buffed | 49.14% | #36 | 0.75% |
| Winter Soldier | Nerfed | 51.40% | #21 | 19.15% |
| Loki | Buffed | 49.77% | #29 | 0.51% |
Change directions reflect the official Season 10 patch notes where stated (Scarlet Witch, Black Cat, Wolverine) and cross-checked patch-note coverage for the rest; "adjusted" means the notes changed the hero without a clean buff/nerf direction. Baselines are Batru's measured Season 9.5 data, not estimates.
Final Season 9.5 standings — the starting point every Season 10 change is pushing against. Mantis closed the season as the highest win-rate hero (60.05%) and gets nerfed; Black Cat closed as the most banned (66.90% of drafts) and gets adjusted.
Batru's numbers come from recorded ranked matches, so Season 10 stats accumulate from the moment servers come back. We don't publish day-one tier claims from thin samples — each page below switches to Season 10 data automatically once its sample clears our quality gate, and shows clearly-labeled final Season 9.5 data until then.
September 11, 2026 at 9:00 AM UTC (2:00 AM PT / 5:00 AM ET / 10:00 AM BST / 6:00 PM JST), with an estimated two-hour maintenance window before servers return.
Gorr the God Butcher, a Duelist. He wields All-Black the Necrosword, raises defeated enemies as Black Berserkers, and his ultimate — the Annihilablade — commands all active Berserkers in a coordinated assault.
Every player drops six divisions (two full tiers) from their final Season 9.5 rank: a Diamond III finish starts Season 10 at Gold III, Grandmaster III at Platinum III. Ranks can't drop below Bronze III, and end-of-season rewards follow your peak rank, not your final one.
Scarlet Witch is fully reworked (she ended Season 9.5 at a 48.02% win rate), Black Cat — Season 9.5's most banned hero at 66.9% — is adjusted, and the patch nerfs top-of-table heroes like Mantis (60.05%, #1 by win rate) and The Hood while buffing sub-50% heroes like Wolverine, Emma Frost, Star-Lord and Loki. Strategist ultimate energy generation also changes role-wide.
Batru's tier list, counters and ban rates are computed from recorded ranked matches and update automatically as Season 10 games accumulate. Until a hero's sample clears the quality gate, pages show final Season 9.5 data with the season clearly labeled — no day-one tier claims from thin samples.
