Whenever Brimaz attacks, create a 1/1 white Cat Soldier creature token with vigilance that's attacking.
Whenever Brimaz blocks a creature, create a 1/1 white Cat Soldier creature token with vigilance that's blocking that creature.
Cast Brimaz on turn three and start attacking immediately, generating vigilant Cat Soldier tokens every combat that can swing again or hold the fort on defense. Build a mono-white go-wide army, then close games with token anthems and overrun effects. The deck plays as an aggressive token/Cats deck that punishes opponents who can't profitably block.
Generates free, board-presence-positive value just by attacking and blocking, with vigilance letting Brimaz do both
Cheap, resilient commander that comes down early and immediately impacts the board
Synergizes with both mono-white token payoffs and the modern Cat tribal package
Vigilance army means you can defend three opponents while still pressuring them
Mono-white means limited card advantage and ramp compared to multicolor decks
Vulnerable to board wipes that erase your token investment in one card
Relies on Brimaz being on the battlefield and attacking to snowball
Tokens are individually small and stall against decks with bigger blockers or fliers
