Elf Grenadiers

Christmas cheer - Whenever you cast a multicolored spell that's white and red, white and green, red and green, or white, red, and gre.n, Elf Grenadiers deals 1 damage to target creature or player.
The elf grenadiers rained screaming death upon the battlefield, locking out the fight on the ground. Eventually, they were slashed to death by a raging werewolf, freeing the rooftop for the epic duel between Halloween Spirit and Santa Claus.
