Official Errata

Iron Fist should say Interrupt instead of Response.

Such a good card! Will become a staple in every protection tech, 3 damage and a stun twice then use him as a blocker or heal him and use him again for 2 damage twice and then a blocker. So potentially 10 damage and stun twice.

Seriously, one of the best protection allies out there especially if you play solo. Getting two stuns and six damage out before he goes is extremely helpful. That's two rounds allowing you to stay in hero mode longer without worry about taking a lot of damage from the villain. Great for heavy hitters like Rhino or upgraded Klaw or upgraded Ultron. Also, useful for high health minions on the board like Mutagen Formula minions, some Masters of Evil, and Titania. Plus you can use him for blocking after the counters are gone.

For multiplayer, he will be key for targetting of the Make the Call when you're needing more stuns and damage.
