Raphael, Ninja Destroyer

Raphael, Ninja Destroyer is legal across every major constructed format but sees essentially zero play outside Commander — the effect is too slow and build-around for Legacy, Modern, or Pioneer, where four mana needs to win the game rather than set up a damage-ping engine. In Standard it's a novelty. Commander is where Raphael lives, specifically in Gruul or Naya shells that already generate persistent damage sources and want a cost-efficient way to turn that synergy into board control. At four mana for a legendary creature, it's the right cost for the format — cheap enough to recast after removal, impactful enough to demand an answer.
