Wicked Visitor
What most enchantment-sacrifice payoffs reward is the sacrifice; this one reads a different verb. It triggers whenever an enchantment you control is put into a graveyard from the battlefield, which is a wider net than a dedicated sac outlet: an aura that falls off when its host dies, a Saga that hits its final chapter and sacrifices itself, a food or a clue-style token if it happens to be an enchantment, an enchantment your opponent destroys with removal. Each of those closes the loop and drains the table. That distinction is the whole reason the trigger sits on the graveyard event rather than on a sacrifice cost: it turns your opponent's own removal into a small tax, and it turns naturally self-sacrificing enchantments (the ones that expire on their own timers) into free damage rather than a resource you have to spend a card to convert. The drain is only one life per event, so the card is a counting engine, not a haymaker: it asks a deck to churn enchantments through the yard in volume rather than lean on any single trigger. The 2/2 body is incidental cover, a cheap chassis to keep the engine on the board while the enchantments cycle around it.
