Vicious Clown
The trigger reads like a go-wide payload attached to a body, but it does something narrower and more deliberate: it rewards you for flooding the board with small creatures without asking them to attack together. Each 2/3 by itself is unremarkable, but the +2/+0 stacks with every qualifying creature that enters in a turn, so the ceiling scales with how many one- and two-power bodies you can chain out in a single window. That construction favors the token-heavy, low-curve deck that empties its hand fast rather than the one that plays a fat threat and swings. The 2-power ceiling on the trigger is the constraint that keeps it honest: your big creatures do nothing for it, so the card asks for a genuinely wide, cheap board rather than a couple of anthem-boosted midrange threats. Because the buff resets at end of turn, the payoff lives entirely in the turn you go off, which means the card is at its best when your creatures and your combat step land in the same breath. It is a common-rarity aggro anchor built to reward committing bodies to the board on your own turn, and it plays best as the finisher for a deck that was already going to do that anyway.
