A search can be used effectively to do one of the following: (1) find a card to use in the current battle, (2) find a card to use in a future battle, (3) see what cards remain in one of your opponent’s piles, or (4) see what cards remain in one of your piles. Play proceeds according to initiative rules. You must wait until the action of the enhancement card is completed before you can interrupt with another enhancement card. Your opponent may not block or play an enhancement while you are searching.
