Gallant Fowlknight

The enters-the-battlefield anthem is a familiar white-aggro engine, but the split here is the interesting part: everything gets the +1/+0, only the Kithkin get first strike. That asymmetry rewards tribal density without demanding it, since the power boost still fires no matter what you've assembled. What it actually buys is a combat-math swing on the turn it lands. Send your team in with a temporary point of power across the board and first strike stapled onto the Kithkin, and blocks that looked even suddenly aren't: the defender either eats damage before it can swing back or takes trades it didn't sign up for. A 3/4 body attached to that trigger means the anthem isn't riding on a fragile shell either; it survives most of what a defensive white deck expects to face and blocks upward well. The catch is that the whole package is a one-shot, spent the moment it resolves, so it wants to arrive when you already have a board rather than as a lead-off play into empty air. That timing constraint is the whole character of the card: a finisher's trigger dressed as a midrange creature, most valuable when it turns a stalled ground into a lethal alpha strike and worth little when there's nothing on the table to pump.
