Rage — Whenever Gau attacks, put a +1/+1 counter on it.
At the beginning of each end step, if a card left your graveyard this turn, Gau deals damage equal to its power to each opponent.
Gau is a mono-red aggro/burn commander that turns graveyard churn into repeatable group damage. Swing each combat to grow Gau with Rage counters, then make sure a card leaves your graveyard each turn—via impulse draw, flashback, escape, or self-exile effects—so the end step burns every opponent for Gau's power. You win through scaling commander damage in combat plus inevitable burn that hits the whole table simultaneously.
Hits every opponent each turn, scaling well in multiplayer pods.
Rage counters make Gau a cheap, fast-growing commander damage threat.
Mono-red impulse draw and flashback naturally trigger the end-step burn with no extra setup.
Cheap to recast at 2 mana, so it stays online through removal.
Doesn't need to connect in combat to deal the burn damage—dodges blockers.
Mono-red lacks card advantage, ramp, and interaction relative to other colors.
The end-step trigger only fires once per turn, capping burn output without power pumps.
Vulnerable to lifegain and fog-style stax that blunts both combat and burn.
