Nyxborn Behemoth

A 10/10 trampler with a twelve-mana tag reads as a curiosity until you notice the entire design is a rebate. Every noncreature enchantment you control subtracts its mana value from the cost, so a shell of Auras, Sagas, and enchantment ramp turns this into a finisher that arrives for a sliver of its printed price. The body is deliberately plain, a large green beater whose only wrinkle is a sacrifice-for-indestructibility line, and that plainness is the point: it answers a chronic problem for enchantment-heavy green, where you assemble a board of permanents that generate value, protect your other creatures, and fix mana while never actually closing a game. Here the pile of enchantments doubles as its own payoff, discounting a threat into existence off the same permanents the deck was already committed to. The sacrifice ability keeps those enchantments earning after they cash out: a spent Aura or a resolved Saga can be fed to grant a turn of indestructibility, so the permanent that shaved the cost can later shrug off a wrath. It is an honest design, not a value engine and not a combo enabler, just a large body that a green enchantment deck was paying for by playing the game it wanted to play.
