Overcharge (X): Where x is the total overcharge
among the creatures and artifacts you control.
Whenever another creature enters battle, you may
deal 1 damage to it. If you do give it overcharge
(3), trample, and haste this turn. It fights target creature.

something far greater" - Zoth, Phanlax Traitor
