Sandcrafter Mage
Bolster's whole conceit was to take the timeless white anthem effect and aim it at a single body, distributing power where the board needs it rather than across the team. This is the cheapest creature in white carrying that keyword without further conditions: a 2/2 that, on entry, drops a +1/+1 counter onto whichever of your creatures has the least toughness. The placement clause is the part worth dwelling on, because it makes the card play differently depending on what surrounds it. Resolve it onto an empty board and the counter lands on the Mage itself, leaving a 3/3 for the cost. Resolve it with a one-drop already down and the counter props up the early threat instead, smoothing a curve that wants its small creatures to survive a turn longer. The wrinkle is that bolster does not target: it instructs you to choose, which means hexproof and shroud creatures are eligible recipients in a way a targeted pump would deny. Two creatures sharing the lowest toughness leave the decision with you; one clear smallest and the board makes the call. That self-narrowing pool is the design's quiet discipline, since the cheapest creature is usually the one most worth protecting in an aggressive shell. It is a modest piece, an entry-level reward for going wide with small white creatures, asking nothing of the deck beyond a board to improve.
