Demon of Death's Gate
The alternative cost is the whole proposition: nine mana buys nothing here that six life and three black creatures cannot buy faster. This is a beater built for the deck that already wants its graveyard full and its life total spent, a payoff for the sacrifice engine rather than a card you cast off lands. Black has long sold its biggest bodies on a discount paid in something other than mana (Phyrexian Dreadnought asked for twelve power of creatures, the school of alternative-cost spells that trades cards or life for tempo), and this sits squarely in that tradition: the printed cost exists mostly as a ceiling, a fallback for the games where the shortcut is not available. The 9/9 flyer with trample is deliberately oversized, large enough that connecting twice ends most games, because the design needs the reward to justify emptying a board of three creatures and nearly a third of a twenty-life total. The tension it resolves is timing: with the right fodder it can land far ahead of when a nine-drop has any business arriving, turning a pile of tokens or expendable bodies into an evasive finisher while the opponent is still developing. The downside is structural and intentional. Pay the alternative cost into a board wipe or a single removal spell and you have liquidated half your resources for nothing. It rewards the deck that treats creatures as currency, and punishes everyone trying to cast it honestly.
