Nashi, Moon's Legacy

Recursion here refuses to cheat mana, and that refusal is the whole design. Where reanimation typically drags a big spell back for pennies on the dollar, this engine exiles a legendary or Rat card from your own graveyard, copies it, and hands you the copy to cast at full price. You are not resurrecting a corpse; you are re-buying something you already thought was worth casting once. The two eligible pools do real work in tandem: the legendary clause turns a board of unique permanents and marquee spells into repeatable value, while the Rat clause is a tribal lever attached to a creature type that almost never gets a payoff of this caliber. Because a copied permanent spell resolves as a token, the loop can leave a new permanent behind while the original card stays exiled, so each swing can widen the board that triggered it. That is why the frame matters as much as the trigger: menace forces two blockers and ward taxes the removal that would otherwise strand a three-mana attack engine on an empty attack step. A trigger that only fires on the swing pays off only if the creature survives to swing again, and the evasion plus the tax turn the second and third attacks from hope into expectation. The graveyard reads as a single toolbox where the legendary and Rat pools overlap, and every legendary or Rat card you bury becomes ammunition for the next combat step.
