Whenever you cast a spell, add . Until end of turn, you don't lose this mana as steps and phases end.
Creatures you control can boast twice during each of your turns rather than once.
Discard a card: Exile the top two cards of your library. You may play those cards this turn.
Birgi turns your spells into mana refunds, letting you chain cheap spells and rituals to generate explosive storm-style turns. You flood the board with cheap red spells, generate mana off each cast, and either burn the table out or assemble a combo. Flipping to Harnfel late gives you a relentless card-advantage engine by trading discarded cards for double draws off the top.
Add fast mana and rituals (Mana Geyser, Pyretic Ritual, Desperate Ritual) plus zero-cost cantrips to maximize cast triggers, then commit to a dedicated combo finisher like Underworld Breach with Lion's Eye Diamond and Grapeshot. Improve consistency with mono-red tutors and card selection (Gamble, Wishclaw Talisman), and trim clunky high-cost cards in favor of more spell density to fuel the engine.
