Lightning Shrieker
A 5/5 flier with haste and trample for five mana reads as a perfectly serviceable beater until the end-step shuffle reframes the entire transaction. This is a creature you rent for exactly one combat: it crashes in the turn it lands, swings for five in the air with trample to spill over a smaller blocker, then folds back into the library rather than sticking around to be sacrificed for value, traded in combat, or caught by a later sweeper. The shuffle reads as the drawback, and in a vacuum it is, but it doubles as a feature for a shell that wants a body it can deploy and forget: nothing for a sweeper to find on a future turn, nothing for an aristocrats player to chew through, the card shuffled away to be redrawn at random. Its whole design lives on impermanence: you pay full freight for a finisher that refuses to stay finished. The trade is pure tempo. You spend five mana for a single evasive swing and surrender everything a creature normally accrues over multiple turns: board presence, blocking, repeated value. That swing is still answerable (a counterspell, instant-speed removal before damage, or a fifth point of toughness in the air all stop it), which is the wager the card forces: is five damage right now worth more than a creature tomorrow?
