Aggressive Polarity

Magneto wants to play his powerful hero-specific cards. They have the Magnetic trait, so Team-Building Exercise is on hand. His events are all Superpower so Deft Focus is also here along with X-Gene. Weapon X and Moria MacTaggert increase card draw to find them when in alter-ego then flipping to hero form.

Angela, Looking for a Trouble, and Spoiling for a Fight summon minions to which many upgrades can be attached: Caught in the Crossfire, Marked, Suppressing Fire. When the minion enters play, find an Tactic upgrade with Air Cover and discard Aggressive Stance to bring an Attack event (Metal Shards) from deck to hand.

Professor X can confuse the villain to allow flipping down to alter-ego and shuffle the last Magnetic card(s) played back into the deck.
