White flicker has always been a reset button first and a value engine second: Cloudshift and Momentary Blink sell you the re-triggered enters-the-battlefield ability, the creature yanked off a targeting spell, the wiped combat damage or shed counters, and then they resolve and leave nothing behind. This one attaches a permanent to the transaction. Blink your own creature to reap the re-entry, and you are also left with a 1/1 Shapeshifter whose changeling status makes it count as a Goblin, a Zombie, an Elf, and everything else simultaneously: it collects the pump from every lord on your side, it answers "sacrifice a Goblin" and "you control a Zombie" prompts alike, and it feeds any tribal payoff regardless of which family the deck committed to. Two effects on one instant, then, but neither of them recurs: the blink is a single trigger and the token is a single body, both spent when the spell resolves. What ties the ceiling to your own board is the target restriction. The exile has to land on something of yours, so this cannot double as spot removal, and its upside scales entirely with how much value your creatures give back on re-entry. Built around enter-the-battlefield triggers, that is plenty: a value blink that resolves at instant speed and leaves a warm, all-purpose body in its wake.
