My opponent was playing The Bloodbile Swarm as their commander in Brawl.

They had a sacrifice outlet and a creature that when entering the battlefield created more treasure tokens than its mana value. Despite me setting to auto pass their stall tactics used my timeout rather than theirs as they perpetually recast the same same creature over and over after sacrificing it. This is a terrible mechanic considering their turn timer never even started flashing. Yes I can sacrifice one of my creatures but I clicked auto pass. Their infinite combo shouldn't negatively affect my ability to play the game when I don't want to click resolve all every single time they cast a creature.

Personally after witnessing this I'd suggest just banning The Bloodbile Swarm. But at the very least the person taking the infinite turn should also be losing their turn timer faster than the person clicking resolve as quickly as possible who cannot play the game.
