DESCRIPTION
the idea is to use lots of cost-efficient zombie creatures that dont mind getting killed (because of undying, rebirth abilities, card removal effects upon dying, etc.) in combination with altars reap and deadly allure. with deadly allure, you can keep trading favorably all day long. it can also be used to bind blockers, and once you have an phyrexian obliterator out, your opponent will have to think very carefully if he really wants to have blockers out there in the first place.
suggestions are welcome!
