Joel Victor, Realmbreaker

Devour (When this card destroys a creature, give this
card a +2/+0. If that creature is a legendary creature,
+4/+0.)
{x} Realmbreaker (Destroy every other card on both
fields that cost the amount of energy used or less.
Destroy the energy this card uses as well.)
Bankai (Can only be activated if Yggdrasil and
Qliphoth both on the field. Half the energy usage of Realmbreaker.)
If you think my power is impressive, then you should
just see me flex.
