Iceman is a strong ally that's a no-brainer for X-Men theme decks and very playable even outside of them. Stunning and confusing minions isn't usually something you would go out of your way to do, but it's a fantastic ability to be stapled onto an ally that's already a fair rate. If a big minion comes down, stunning it gives you an extra turn to accumulate damage. If you are 2 turns away from killing the villain, stunning a newly drawn minion lets you focus your damage on the villain over that 2-turn window. You can keep an extra minion in play before using an AoE attack. All these little uses add up and make Iceman a versatile ally that will still get you 4 damage and a block even if no minion is drawn. This makes Iceman a protection staple in my book, and you need a compelling reason to leave him on the sideline.
