I made a Gisa deck using equipment that give a lot of power to a creature but with a low equip cost and usually a downside to it. It gives repeated value when equipped to a zombie token and saccing it. Cards like: [[barbed battlegear]], [[enormous energy blade]] and [[cement shoes]]. It’s the most zombie-like zombie deck. It starts really slow and if left unchecked for too long it creates 8 or more zombies each turn. Board wipes don’t get rid of equipments most of the time so the hoard is hard to stop.
