Rule 358.3.a

If a Game Effect prevents the performance of a game action, that effect doesn’t prevent cards and abilities that instruct a player to perform that game action from being played or finalized. On resolution, that game action will be skipped as it is an impossible instruction. Example: A player plays Here to Help when their opponent controls a Mageseeker Warden at a battlefield. Here to Help is legal to play under these circumstances. On resolution, no unit will be played.
