Yogg'Saron, the Lucid Dream

Menace, trample, protection from colored spells.
When you cast Yogg'Saron, each opponent exiles a permanent and a card in their hand. Whenever Yogg'Saron attacks, target player exiles the top 10 cards of their library. If Yogg'Saron leaves the battlefield by any means, it is shuffled into its owner's library instead.
Sacrifice Yogg'Saron: Take control of target opponent during their next turn.
