Amethyst Dragon // Explosive Crystal
The reason to run this is the Adventure half. Explosive Crystal deals four damage split however you like among any number of targets: flexible burn that answers a cluttered board, a lethal face plus a mana dork, or a single fat blocker with equal ease. The part that lifts it above a stapled-on removal spell is where the card goes afterward. Casting the sorcery exiles it rather than filling the graveyard, so the burn doesn't consume the Dragon; a 4/4 flier with haste waits in exile until you actually want to attack. Two halves, one card slot, cashed in on whatever schedule the game dictates.
The split-damage mode isn't free. Six mana for the creature side, layered on top of the earlier spell, means removal and threat almost never resolve on the same turn; you spend across two moments in a game rather than compressing them into one swingy sequence. That separation is the design. The burn earns its keep when you have no board, the flier closes when you do, and the card stays live in both states without asking you to pick between answer and pressure back at deckbuilding. Adventure has always been about this kind of double duty, and this is a clean instance of it: the removal you cast when you're behind and the clock you cast when you're ahead, folded into one draw. It reads like filler until you count how few cards cover both game states at once.
