Rockcaster Platoon

A green-activated anti-flyer gun stapled to a white bruiser, and that color split defines everything it can and can't do. The body is mono-white: a 5/7 wall that holds the ground all day and trades up on stalled boards. The repeatable damage ability charges a green cost, marking this as a card cast on the white side of a deck but fueled by green mana, a two-color identity that points it squarely at a green-white shell with the lands to fire the ability more than once a turn. That activation is pointed rather than clean: it deals 2 to each flying creature and each player, sweeping aerial attackers and blockers while chipping every life total, but it never touches a ground creature. The design reads as an answer to flyer-heavy aggro, a fixed source of repeatable air-clearing that costs no spell slot, attached to a frame sturdy enough to wait while you build mana. The drag is the cost: four generic and a green every time, to clear two toughness of evasion, slow enough that it never runs away with a board the way a cheap sweeper would. It also burns your own fliers and your own life total, so the player who leans on it commits to a ground plan and a manabase that can keep paying the green half. A creature that wants a lot of land and a deck shaped to ignore its own downside is a narrow ask, which is why it lived as a curve-topper and not a staple.
