Conspiracy

The pure type-changer, stripped of any other function. Where most tribal payoffs ask you to commit to one creature type and then reward you for filling a deck with it, this enchantment inverts the cost structure: it doesn't care what your creatures actually are, only what they count as once it resolves. The chosen type overwrites every creature you control, every creature spell you cast, and every creature card you still hold in hand or graveyard, making it both a retroactive and forward-looking declaration rather than a one-time boost. The design tension lives in the scope of "creatures you own": it reaches past the battlefield in a way few enchantments of its era did, turning a Goblin lord into a global enabler for whatever your library happens to contain. The catch is that it pays nothing on its own. It is infrastructure, not a payoff, and it asks the deck around it to supply both the lords that benefit and the tribal hate that suddenly turns one-sided when your entire board reads Sliver or Zombie regardless of art. That separation of "what makes the type matter" from "what sets the type" is the quietly radical part: most tribal cards fuse those two jobs, and this one refuses to. The refusal has kept it a toolbox piece for combo and tribal builders long after its original home environment faded.
