Twining Twins // Swift Spiral

Cast Swift Spiral first and you get a white instant that exiles a nontoken creature and returns it at the beginning of the next end step: a flicker that resets an attacker or blocker mid-combat, dodges a removal window on your own board, or re-triggers a valuable enters-the-battlefield effect. The return timing is the wrinkle worth studying. Because the target comes back at the beginning of the next end step rather than yours, blinking a creature on an opponent's turn blanks their kill spell and still leaves the creature around going into your own turn. What ties the two halves together is that the spell banks its own follow-up: once Swift Spiral resolves, Twining Twins waits in exile rather than in hand or graveyard, ready to deploy when the four mana arrives as a 4/4 flier with vigilance and ward that attacks and defends on the same turn and taxes any answer. The design leans on the payment order, spending the cheap utility early and cashing the threat late, so a single card splits into two independent plays spread across a game. It is a two-in-one built for the grind, and the exile mode earns its keep long before the body ever hits the table.
