Projected veto

likely picks & bans
ihow this projection works

A hypothetical veto for this matchup, projected from how each team has picked and banned before (Bo3, Marsborne vetoes first). It's a guide to the likely map pool and each side's win% on those maps, not a guarantee: teams adapt to the opponent and the event.

Iowa Stormboar habitually bans Inferno, Marsborne's strongest maps (Inferno, Mirage, Anubis all ≥60%). That's a standing habit (Inferno 14/24), not an opponent read, so expect Marsborne to fight the veto for Inferno.
