Whenever another Bear you control enters, choose one —
• Put two +1/+1 counters on target Bear.
• Target Bear you control fights target creature you don't control.
Ayula is a mono-green tribal deck built around the surprisingly deep pool of Bears (and bear-makers). Every Bear that enters triggers Ayula, letting you snowball +1/+1 counters or fight away threats. Flood the board with bears, pump them tall, and beat down or go wide with anthem effects.
Cheap two-mana commander that's hard to answer permanently and immediately impacts the board
Built-in removal via the fight ability keeps the board clear
Counter synergies snowball quickly with proliferate and doublers
Mono-green gives access to the best ramp and easy mana
Bear tribe is shallow and many payoffs are mediocre creatures
Mono-green lacks interaction with the stack and struggles vs. flyers/control
Fight ability requires you to control a Bear and can lose your creature to deathtouch/big blockers
Heavy reliance on Ayula's triggers makes it vulnerable to board wipes and removal-light recovery
