Core Set 2020 Promos

Because fighting isn’t combat damage, trample has no effect during the fight.

If the target of Voracious Hydra’s second mode isn’t a legal target as the ability resolves, or if Voracious Hydra has left the battlefield, neither creature will deal or be dealt damage. The ability won’t change to the first mode if the target is illegal.
