Card sounds may differ from in-game as they get updated.
Summon - Does something when played
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.
Scout - Look at the top card of your deck. You may put it on the bottom.
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.
