completely ignoring the potential strength/weakness of the card, i LOVE the concept. reversing time on a mummy makes it a pharaoh, brilliant! reversing time on an undead creature becomes the original creature. hopefully a card will complete the idea soon, turning creatures into zombies (maybe by biting them on the neck)
*ability* zombie:bite another creature with equal or less HP's, that creature turns into a zombie in one turn
just a fast example. looking forward to my zombie theme deck
oh, and a weapon called "shotgun" zombies one weakness and natural enemy
edit, skull buckler! more zombie cards please!
