Saprazzan Bailiff

Most graveyard hate of its era was a clean transaction: exile the offending cards and walk away. This Merfolk instead writes an IOU. The enter trigger banishes every artifact and enchantment from all graveyards at once, but the leave trigger does not return those exiled cards; it returns whatever artifact and enchantment cards happen to be sitting in graveyards the moment the body departs. The whole strange engine lives in that mismatch. The exile is a single timing-locked sweep, not a lock that lingers: the instant it resolves, nothing stops either player from refilling their graveyards again, and the Bailiff does nothing to slow them down. So the longer it lives, the bigger the payload waiting on its departure, and when it dies, bounces, or gets sacrificed, that pile floods back into owners' hands all at once, the caster's opponent included. The departure trigger threatens both players, the very property that has largely retired this kind of symmetric downside: it is trivial to turn against the player who cast it. The wrinkle cuts both ways, though, since the cards come back to hand rather than to the yard. Kill the Bailiff into your own graveyard recursion and you hand the artifacts and enchantments straight back to their owner, undoing whatever staging you had done. It is disruption with a fuse attached, a stay of execution rather than a verdict. The two triggers, not the 2/2 body, are the entire reason the card exists; five mana on a small Merfolk tells you the enters-and-leaves package was always meant to carry the slot.
