Sorinjace, Master of Minds

Partner with Aryanf, Herald of the Wild (When this creature enters the battlefield, target player may put Aryanf, Herald of the Wild into their hand from their library, then shuffle.)
Whenever a creature you control deals combat damage to a player, exile the top card of that player's library. You may cast that card without paying its mana cost if its converted mana cost is less than the amount of damage dealt.
