Path to Redemption

Pacifism with a back door. For two mana, the enchanted creature can neither attack nor block: soft removal that shuts a threat out of combat without ever putting it in the graveyard. What separates this design from the parade of "can't attack or block" auras is the sacrifice clause, which lets you cash the parked creature in later. Five mana and the Aura itself exile the enchanted creature outright and leave a 1/1 Ally token behind, converting a temporary lock into a permanent answer. That changes how the card ages across a game: early on it is a tempo play; later, when five mana is trivial, it becomes an exile effect that also nets a body. The your-turn-only restriction on the activation is the leash. Because it is limited to your turn, you cannot spring the exile on your opponent's turn in response to a sacrifice or a bounce spell aimed at the creature, so a threat can slip out of your Aura before you ever get the chance to convert it. The token is the flavor payoff of the name, a redeemed convert rather than a corpse, but mechanically it also feeds the tokens-and-Allies builds that want bodies more than they want clean removal.
