Vance, Murder Marauder

+1: Each opponent exiles the top card of their library. For each card that shares a color exiled this way, create a 1/1 black rouge.
-3: Search your library for a card, put that card into your hand, discard a card at random, then shuffle your library.
-7: You get an emblem with "If an opponent would draw a card except the first one they draw in each of their draw steps, they take 3 damage instead."
