Iymrith, Fléau du Désert

If a spell or ability an opponent controls targets Iymrith, Desert Doom while it is tapped, finding a way to untap it in response will not cause its ward ability to trigger.

If a player casts a spell that targets multiple permanents their opponent controls with ward, each of those ward abilities will trigger. If that player doesn't pay for all of them, the spell will be countered.
