Garruk's Horde

Card advantage that lives on the battlefield instead of in your hand: the Horde turns the top of your library into a deck-wide creature engine, and the bargain it strikes is plainly stated in the body. A 7/7 trampler for seven is a fair fight by itself, but the real proposition is that every creature you peel can be cast straight off the top without ever passing through your hand. The cost stays the same and the timing stays the same (sorcery-speed creatures still wait for your main phase); what you gain is a hand that never empties, since each creature draw resolves into a play rather than a card. The friction is that the engine only works for creatures: a noncreature card on top sits there until you draw into it, and the constant reveal hands the opponent perfect information about your next play. That asymmetry is the design lever. In a deck stuffed with creatures, the revealed card is almost always something you can deploy; in a mixed deck, the reveal becomes a liability and the effect stalls behind a brick. It belongs to the small family of green fatties that read the top of your library aloud, a tradition that runs through Oracle of Mul Daya and Vizier of the Menagerie, but the Horde is the bluntest of them: no scry, no manipulation, just a big body and an open door for whatever creature you find on top.
