Plasma Overcharge aka Please No 1's

Our goal is to maximize the damage of our multi-hit cards: Firepower and Royal Flush. Gambit's Charge de Card ability, Warrior Skill, Aggressive Energy and Keep Up the Pressure charge both attacks, while Directed Force only works with Firepower (and Charged Card), hence the single copy.

Gambit has one weapon in his kit, but we need 2 more in play to maximize Firepower. There are a few you could use, but Plasma Pistol can be played with The Power in All of Us and does something outside of Firepower.

With every source of additional damage, Firepower can deal 3x12 = 36 damage and Royal Flush can deal 3x7=21 damage. A fully-charged 13-damage Charged Card is no slouch either, dealing with toughs, minions and tough minions.

Colossus & Rogue defend, Beak, Storm & Psylocke help with threat, and Magik & Sunfire solve problems.
