Electro, Assaulting Battery

—

Electro is a 3cmc flying 2/3 that generates {R} whenever you cast an instant or sorcery and crucially lets you bank red mana across steps and phases — effectively a red mana battery for spellslinger and storm-style decks. His LTB ability converts stockpiled unspent red mana into a face-damage burst via {X} payment, making him a combo-oriented burn payoff. He's most at home in mono-red spellslinger or storm shells where he accelerates into and rewards casting chains of instants/sorceries.

• The 'don't lose unspent red mana as steps and phases end' static ability is exceptional in spellslinger shells — it lets Electro bank mana generated from multiple spell-casts across an entire turn cycle, enabling an enormous LTB X-damage payout.

• Electro's LTB trigger reads 'when you do' after paying {X}, meaning you must successfully activate the payment for the damage to resolve — if you can't pay any X, the trigger does nothing even if Electro leaves the battlefield.

• Electro pairs especially well with sacrifice outlets or blink effects: you can proactively cash in his LTB damage at a chosen moment rather than waiting for opponents to remove him.
