Skyskipper Duo

Blink effects usually point across the table: exile the opponent's blocker, reset your own creature to dodge a removal spell. Here the exile clause aims exclusively at your own board and returns the creature at the following end step, which turns a defensive tool into a value engine. Any creature worth flickering fires its enter-the-battlefield ability a second time, and because the returned body comes back before your untap, it is available to attack the next turn rather than sitting summoning-sick. The "up to one" wording keeps it from stranding in your hand: with no worthwhile target, it simply resolves as a 3/3 flier and asks nothing of the board, so the reset is pure upside layered on a functional creature. That optionality is what lets it slot into a curve without becoming a dead card on empty boards. Because the effect rides on a permanent instead of vanishing after a single flicker spell, the flying body keeps earning its cost even on the turns the reset does little; it is built for decks that want to re-trigger enter-the-battlefield abilities without spending a slot on a fragile dedicated enabler.
