A flier that pays out the moment it stops flying. The trick is that bolster fires on death, not on entry or attack, which inverts the usual logic of a chump-blocker: trading this body in combat or feeding it to a kill spell is not a loss but a transaction, moving two +1/+1 counters onto whichever creature you control has the least toughness. That choice clause is the design's quiet steering mechanism. Bolster always lands on the most fragile thing on board, so the counters tend to find a token, a mana dork, or a one-toughness aggressor that suddenly becomes a real clock, rather than padding something already large. And because bolster chooses rather than targets, that distribution happens regardless of shroud or hexproof; there is nothing for the recipient to protect against. The body itself is unremarkable evasion, but it is built to be spent. A trade in combat gives you the bolster; destruction gives you the bolster. What denies the trigger is any answer that removes the creature without killing it: exile, bounce back to hand, or an aura that simply switches it off and leaves it stranded on the battlefield. That is the seam an opponent has to find, because straightforward removal only completes the transaction. It belongs to the small family of creatures whose death is the spell, where the counter package is the reason the card exists and the wings are just the delivery system.
