Your Shifted units emerge one turn sooner.
Card sounds may differ from in-game as they get updated.
Warp - You can see cards with Warp when they are on top of your deck, and you can play them as if they were in your hand.
Shift - When played, you may instead pay the Shift cost. Shifted units can't attack, block, or be selected until they emerge.
Emerge - After three turns, Shifted units emerge and get Unblockable that turn.
