When I tried to find all the Hare Apparent in my opponent's deck with Deadly Cover-Up, it took me a minute or two to select all of them from their deck. This can happen with basic lands, or any other card that is allowed in unlimited numbers in a deck.

That seems unfair when turns are limited to 30 seconds. I don't enjoy tapping and scrolling 50+ times, particularly on mobile.

Please add a "find all" button to actions that can find all (or many) cards in a deck, graveyard, or hand.
