This card combos really nicely with Colossus. Lowers his cost even further, Colossus defends with his Tough status & can be used again later for an attack 3 and another defend. Polaris works well with this card too, she even gives the extra flexibility of allowing the player to choose which X-Man receives the Tough status
Play only if your identity has the X-MEN trait.
Hero Interrupt (defense): When an enemy attacks, put an X-MEN ally into play from your hand. Exhaust it and declare it the defender for this attack.
