Alistair, the Brigadier (Extended Art) (Foil) - Doctor Who

Whenever you cast a historic spell, create a 1/1 white Soldier creature token. (Artifacts, legendaries, and Sagas are historic.)

Whenever Alistair attacks, you may pay . If you do, creatures you control get +X/+X until end of turn, where X is the number of historic permanents you control.
