Veteran Survivor

Survival keys off a condition most white one-drops never track: whether the body is still tapped by the time the second main phase arrives. That inverts the usual math on a small attacker. You want it swinging, but the trigger only checks for tapped, so the graveyard exile fires whether the creature attacked, was tapped for a value effect, or spent the turn safely out of combat entirely. Each trigger moves one card, so the payoff accrues across turns rather than arriving in a burst: reach three cards exiled and the 2/1 becomes a hexproof 5/4 the opponent can no longer target. That threshold is the whole tension. The exile is the incidental graveyard interaction white has always run thin on, and it doubles as a self-timer, arming a threat that then walls itself off from targeted removal at exactly the moment it has grown large enough to matter. The clock stays honest: it takes three tapped second main phases to reach hexproof, and each of those is a window the opponent gets to answer the creature before the door shuts. What makes the ability worth building around is that both halves point the same direction: incidental graveyard hate on the way up, a protected finisher at the top, both gated behind the requirement that the body keep showing up tapped and alive.
