Trample

Whenever Borborygmos and Fblthp enters the battlefield or attacks, reveal the top 3 cards of your library. Put up to two land cards with different names from among them onto the battlefield and put the rest on the bottom of your library in a random order.

Discard a land card: Exile Borborygmos and Fblthp. Return it to the battlefield at the beginning of your upkeep.
