Phyrexian Deathrite

Deathtouch
When Phyrexian Deathrite enters, each opponent discards a card.
Whenever Phyrexian Deathrite deals combat damage to a player, that player discards two cards, unless they discards a land card.
Whenever an opponent discards a card, if it's a land, add one mana of any color, otherwise, exile it.
You may may cast cards, exiled with this creature, and can cast them as though they had flash.
