Rage Liberator

Haste, First strike, Vigilance, Trample
Death by exhaustion: if this creature has to die
while blocking, it destroys the attacking creature
it have blocked by causing damage equals to X
times it's strength, X the minimal multiplier
needed to deal more damage than the attacking's creature toughness.
If excess damage is dealt this way, this damage is
dealt to the player as if it was an attack with
trample.
