Wickerfolk Thresher (U 207 DSK)

Delirium — Whenever Wickerfolk Thresher attacks, if there are four or more card types among cards in your graveyard, look at the top card of your library. If it's a land card, you may put it onto the battlefield. If you don't put the card onto the battlefield, put it into your hand.
