Magnetic Aegis

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.

Ready for a Fight allows stree-free slip to alter-ego, shuffling the top 3 cards in the discard pile into the deck with Erik's Surivivor ability. Enhanced Physique makes the necessary strength resource more consistently available.

The Magnetic Bubble provides significant protection from damage to play both Bait and Switch to manage threat on the main scheme as well as Taunt to draw more of his powerful magnetic cards. Otherwise, with Wrapped in Metal in hand, play Come Get Me Bub to find a minion to lock down then heal any damage and gain a tough status card.

Armor and Polaris provide further defense options. Hope Summers brings to hand a superpower card, like Magnetic Missile when a minion with Wrapped in Metal is sitting in play.
