The Eighth Doctor

Historic is one of the widest supertype umbrellas in the game: every artifact, every legend, every Saga counts, and this card turns your graveyard into a second hand full of them. The mill-three on entry is not damage, it is fuel; it seeds the yard you are about to replay from. The engine that follows is the real design: once during each of your turns, you get a land drop or a permanent cast out of the graveyard, and each thing you retrieve carries a self-exile clause so it cannot be looped back a second time. That single restriction is what keeps the ability from becoming an infinite recursion loop with any blink or sacrifice outlet, and it forces the value to come from breadth rather than repetition: you want a graveyard stocked with different historic permanents, not one you plan to recur forever. The cadence matters too. A land drop from the yard is free in the sense that it does not compete with casting a spell, but the permanent-from-graveyard mode does spend your once-per-turn window, so every turn becomes a small choice about which line of recursion advances your board fastest. Blue-white rarely gets a grindy graveyard engine that plays to the top end of a permanent-heavy deck; this one hands the color pair a recursion loop it usually has to splash black to touch, and prices the power in a clean, one-shot-per-card exile tax.
