Silver Surfer, Cosmic Voyager

This body pulls off a blink at instant speed, aimed inward. Flash plus flying makes the 5/5 an end-of-turn ambusher, but the entry trigger is what earns the slot: exile any number of your other permanents and hand them back when the turn winds down. That delay is the strategic axis. Held until an opponent's turn, the flicker dodges targeted removal in response, resets creatures marked for death, retriggers a board's worth of enter-the-battlefield effects, and untaps nonland permanents you saved by pulling them off the table. Because the return waits rather than resolving immediately, the coverage is broad: exile a permanent about to be sacrificed, exile a creature to strip counters or auras, exile a lock piece to sidestep a wrath, then reclaim all of it for no additional cost. The land clause is the single tax on the play, since any card with a land type returns tapped and cannot power a same-turn mana burst. Flicker effects usually cost a card and a hard-cast body; folding one into a flashable evasive threat means you rarely have to choose between advancing your board and protecting it. The hazard is that everything leaves in a batch and comes back in a batch, so a mistimed cast can strip your own defenses for a full turn. Played with foresight, it converts your permanents into a reserve you can pull back and redeploy on demand.
