A cEDH-style tempo deck that floods the board with cheap, evasive and recursion-friendly creatures, using Massimo to turn each creature entering into a carrier for a one-mana instant or sorcery from the graveyard. When that creature deals combat damage to a player, the spell is copied and cast for free. Opponents are locked out of interaction during the attacking turn while stax-tax pieces and free counterspells protect the board. Underworld Breach combos with Brain Freeze and Lion's Eye Diamond, Lotus Petal or Electro plus Burning Inquiry give an instant-speed win when assembled. How it wins: The deck chips in with evasive, Massimo-enhanced attackers that recast cheap spells and build Treasure and cards, then closes the game with an Underworld Breach loop that mills every opponent out or drains them through Electro. Key roles: - Massimo spell carriers: Cheap creatures and token makers keep entering, so Massimo exiles a one-mana spell onto each one. Delney doubles the triggers from small bodies and makes them hard to block, which turns connections into free Lightning Bolts, Brainstorms, Silences or Great Train Heists. (Delney, Streetwise Lookout, Young Pyromancer, Third Path Iconoclast) - One-mana spell suite: A dense package of mana value 1 cantrips, counters and removal fills the graveyard as fuel for Massimo. Each spell also triggers spell-cast payoffs like token makers, Treasure and the surveil engine. (Brainstorm, Lightning Bolt, Careful Study) - Creature tutor chain: Recruiters fetch small-power or small-toughness creatures, and each new body re-triggers Massimo, so the deck can assemble lock pieces or combo enablers on demand. (Imperial Recruiter, Recruiter of the Guard, Ranger-Captain of Eos) - Turn-lock and protection: These effects stop opponents from casting spells during the combo or attack turn, backed by free counterspells and an uncounterable-spells effect. (Grand Abolisher, Voice of Victory, Fierce Guardianship) - Opponent-tax value engines: Punisher draw and Treasure pieces profit whenever opponents cast or draw, fuelling fast mana alongside an artifact-heavy ramp base. (Rhystic Study, Smothering Tithe, Esper Sentinel) - Breach combo package: Graveyard-filling tutors like Gifts and Intuition set up Underworld Breach loops. Free mana from zero-cost artifacts or Electro's red-mana engine recasts Brain Freeze or Burning Inquiry until everyone is milled or Electro's leave trigger finishes. (Underworld Breach, Brain Freeze, Lion's Eye Diamond)
