Thud

A pared-down heir to Fling, and the sacrifice-a-body-for-its-power effect at its most literal: one red mana, one creature fed to the spell, one number aimed at any target. The difference between the two is timing rather than range. Both hit any target, but Fling is an instant and this is a sorcery. That speed restriction is the whole story of how the card plays. You cannot hold it up in response to a removal spell aimed at your threat, and you cannot fire it mid-combat to salvage a creature that got chump-blocked. It resolves on your own turn, on your own terms, so the plan has to be built in advance rather than improvised: grow one enormous attacker, then convert its power straight to the face before the opponent gets a window to interact. The timing wrinkle worth knowing is that the sacrifice is an additional cost paid on cast, not an effect on resolution, so the creature is already in the graveyard by the time any player can respond to the spell. The damage keys off the creature's power as last seen on the battlefield the instant it was sacrificed, which means every pump spell, aura, or pile of counters has to land before you announce Thud, not after. Keywords like trample or double strike do nothing here; they change how a creature fights, not how large its power number is. The reward is for players willing to invest everything in one oversized body and cash it out directly, turning the creature into a projectile and skipping combat entirely.
