Nighthawk, Dark Defender

A tribal payoff dressed as an anthem engine, and the distinction matters. The trigger fires not only off this card but off every other Hero you control, so the payoff grows the more the battlefield fills with the type: each new Hero entering becomes a +1/+1 kicker aimed wherever you need it. That routing is the design's real hook. Because the pump targets any creature, not the entering Hero itself, it turns a go-wide creature type into a growth engine, dropping a point of power (until end of turn) onto whichever attacker you want to size up. The two-mana cost and evasive body keep it playable as a curve-filler, but the ceiling lives entirely in the second line of text, where a repeatable, retargetable pump wants a deck built to chain Hero entries rather than a single blowout. A static lord hands out a team-wide +1/+1 passively and forever; this one asks you to keep bodies flowing onto the battlefield to keep the pumps coming, then decide each turn where the extra power lands. The pumps arrive whenever the Heroes you deploy enter, and a Hero flashed in during combat can serve as a combat surprise, so the value is renewed each turn: a board that can grow every time you add to it. It is the reward a Hero deck is built to feed, not a standalone threat.
