Stalactite Dagger

Changeling has always lived on creatures: a body printed to answer to every lord and typal payoff you own at once. This Equipment migrates that trick off the body and onto a piece of gear, then splits it into two payments. The enters trigger mints a 1/1 changeling token, a self-contained tribal member that qualifies for whatever you happen to be building around, so the card contributes to the board even if you never spend the equip cost. The equip half then hangs "all creature types" onto a genuine threat, with a +1/+1 riding along, so a real payoff creature suddenly answers to lords it was never printed to care about. That is the sharper half of the design: the token is already every type on its own, but porting the type-fixing onto a creature that matters is what turns a warm body into a universal tribe member, and lets the effect walk from one creature to the next as the first host dies. Being every type cuts both ways, and the design does not soften it: an all-types creature slips past "creatures that aren't [Type]" sweepers but becomes legal quarry for every type-specific hate card in the format, so the equipped threat grows both more relevant to your lords and more exposed to the opponent's answers. The sorcery-speed equip frames all of this as a deckbuilding commitment rather than a combat trick, which is the correct home for a payoff this typal.
