Corvus Academy of Arts
Temporary Can't Attack When your Hero would take damage, they take no damage. Use 1 ammo
The Corvus Academy of Arts is a SupportMonkeycard in Bloons Card Storm, introduced in version 4.0. The player cannot control its attacks manually. Each time the player would've leaked to a Bloon, it consumes 1 Ammo to prevent the Hero from losing HP from the Bloon. When it runs out of Ammo, it automatically removes itself at the end of the turn.
