Neighborhood Guardian

The trigger reads like an anthem but behaves like a payoff engine, and that gap is the whole design. It grants no static team buff; it fires once per small creature that arrives, handing a single +1/+1 to any one creature you choose. That targeting freedom is where the card gets interesting. You can stack every pump onto one attacker to force through a lethal swing, or spread the bonuses to keep blockers alive, and because each buff expires by turn's end it rewards flooding the board in one big turn rather than grinding value across many. The power cap on the entering creature is the cost of admission: it locks your heavy hitters out of feeding the engine while making a wide bench of tokens, one-drops, and utility bodies suddenly relevant to your combat math. It descends from the cheap white creatures that reward going low and going wide, but it trades the passive, always-on stat line those offer for something more surgical and more explosive on a chosen turn. The catch is that it does nothing the turn it lands unless another small creature follows; it wants to be cast into a plan already in motion, not deployed off the top. Built as an uncommon-tier engine for token and go-wide white decks, it is a payoff that keeps asking to be fed.
