You can't cast Rakdos unless an opponent lost life this turn.
Flying, trample
Creature spells you cast cost less to cast for each 1 life your opponents have lost this turn.
Deal damage to opponents to unlock massive cost reductions, then dump expensive creatures (often huge or free) onto the battlefield for explosive turns. Early game you ping opponents with pingers, Shocklands, and aggression, then chain out big bodies and game-enders once life loss accumulates. You win by overwhelming the board with cheated-out fatties and combo payoffs.
Add reliable repeatable pingers (Spear Spewer, Cunning Sparkmage, Goblin Sharpshooter) and incidental life-loss sources so the engine never stalls. Lean into high-value bombs—It That Betrays, Artisan of Kozilek, Ulamog—plus reanimation to abuse the discount, and include fast mana (Sol Ring, Mana Vault, Jeweled Lotus) to deploy Rakdos and follow-ups early. Tighten the mana base with fetch/painlands that ping yourself or opponents and add protection like Lightning Greaves to keep Rakdos sticking.
