A-Elderfang Ritualist
The Arena rebalance (the "A-" prefix) is the tell that something about the original ran too hot, and here the change hides in a single word: the paper version returns the card unconditionally, while this version asks you to exile the body first. That exile clause is the whole tension. It converts what could be a repeatable graveyard engine into a one-shot, because firing the recursion consumes the card itself: reanimate the Ritualist and you can trigger the death effect a second time on the original, but if you took the exile on the first pass, that copy is gone from the yard for good. What the trigger buys is a modest but reliable rebate on an Elf tribal shell, letting a 3/1 that trades in combat cash out into a fresh copy of your best Elf or a Tyvar card from the graveyard. The design is doing familiar aristocrat-adjacent work (a body that wants to die and hands you value on the way out), but the target restriction keeps it from being generic: it reaches only Elves and Tyvar, so it rewards a committed tribal build rather than slotting into any sacrifice deck as raw card advantage. Gating the recursion behind self-exile rather than a plain "return a card" trigger is the meaningful lever between the two printings, and it is the difference between a value creature and a piece you can grind indefinitely.
