When March of the Canonized enters the battlefield, create X 1/1 white Vampire creature tokens with lifelink (Damage dealt by the creature also causes its controller to gain that much life.). At the beginning of your upkeep, if your devotion to white and black (Each or in the mana costs of permanents you control counts towards your devotion to white and black.) is seven or greater, create a 4/3 white and black Vampire Demon creature token with flying (This creature can't be blocked except by creatures with flying or reach.).
