Kaleidostone

A two-mana artifact that replaces itself the moment it lands, then quietly waits to become a Chromatic Star with a five-color payout. The first ability is the real reason it goes in decks: pay two, draw a card, and you have thinned a slot without sacrificing card advantage. The mana ability is mostly a formality. Five mana plus the tap plus the artifact itself to produce one of each color is a rate nobody pays for fixing; the value is that it can, in a pinch, fix any spell in a five-color pile while never being a dead draw. That separation is the whole design idea. Where most rainbow-fixing rocks ask you to eat a card disadvantage for the privilege of casting off-color spells, this one front-loads a cantrip so the fixing rides along for free. You are not running it to ramp into wedge-color bombs; you are running it because it is a cycler that happens to leave a five-color tap-land's worth of color identity behind if you ever genuinely need it. It is a deliberately humble card: cheap to deploy, never card-negative, and willing to be ignored as a mana source most of the time. The lineage it sits in is the small family of artifacts that buy you a card up front and a contingency in the back, and it is among the most forgiving of them precisely because the floor is "draw a card."
