Mogis, God of Slaughter

The opponent never gets a comfortable answer to the upkeep trigger, and that is the whole design. Two damage or a creature, every turn, on every opponent: in a duel it is a slow burn, but at a multiplayer table it compounds into a tax nobody can pay forever. Sacrifice is the cruel half of the choice, because it sidesteps indestructibility, hexproof, protection, and every other defensive layer a board might rely on; the opponent surrenders a creature of their choice, which means it eats their worst blocker and never their best one. The Theros gods all share the devotion clause that gates the body, and Mogis carries the most aggressive interpretation of it: the 7/5 is almost beside the point. The clock runs whether or not devotion to black and red ever reaches seven, so the creature half functions as upside rather than the plan, an indestructible finisher that arrives only after the enchantment has already been grinding. That inversion is what separates Mogis from the larger gods whose bodies are the payoff. Here the upkeep trigger is the engine and the body is the bonus, which makes it a punisher that costs almost nothing to leave on the table and asks the opponent to bleed for the privilege of ignoring it.
