Storm Sculptor

The unblockable body is the obvious draw, but the enters trigger is what decides whether the card earns its slot. Returning a creature you control to hand is written as a mandatory bounce, so in a vacuum it costs you tempo: you have to replay something just to deploy a 3/2 that connects every turn. The design assumes you would rather not pay that flatly, and pushes you to convert the bounce into a feature. Pick up another creature with its own enters trigger and the downside becomes a second activation; reset a creature saddled with an unwanted counter or a hostile aura and it becomes a cleanup step; even scooping a spent mana dork back up on a turn you no longer need the extra body can be worth the click. Cast normally it has no flash, so on its own it arrives at sorcery speed and reads as a proactive tool rather than a response to removal; hand it an instant-speed entry through some other effect, though, and that mandatory bounce becomes a way to blink one of your own creatures out of a spell's path. Absent any of that, the trigger simply taxes you, and the clock underneath is fair but modest. That gap between floor and ceiling is the whole point: it belongs to the family of evasive blue bodies that arrive with a recursion hook attached, where the value lives in what you choose to return, not in the creature standing in front of you.
