Dreamer, Void-Scarred

Hexproof from Colorless Eternalism - When Dreamer, Void-Scarred attacks, exile up to one artifact you control and put an Eternal counter on it. If you do, search your library for an artifact with mana value 1 greater than a card exiled with an Eternal counter, put it onto the battlefield, then shuffle your library.{/fontsize-19}
