Alora, Merry Thief

The tension every unblockable enabler has to resolve is that giving a creature evasion for a turn is worth almost nothing if the attacker doing the damage is unremarkable, and worth too much if it just clears the way for a hasty finisher. This design splits the difference by welding a bounce clause to the evasion: the attacker you make unblockable returns to its owner's hand at the beginning of the next end step. On its own that looks like a downside, but it is the pivot the whole card turns on. Aim the ability at one of your own creatures with a valuable enter-the-battlefield effect and the return-to-hand rider stops being a cost and becomes a loop, sending that creature home so you can replay it next combat while still connecting for damage this one. The "up to one" keeps the trigger optional turn to turn, so you are never forced to send back a board you would rather keep swinging. On a fragile 3/2 body, this is an enabler and never the closer, which is exactly why the Choose a Background frame carries the design: the second commander slot is where the deck decides what all that unblockable damage and end-step recursion is actually paying for. The card wants a partner that either supplies a payload worth recasting every turn or converts cheap unblockable connections into real pressure. It is built to be steered by that choice rather than to dictate it.
