Wild Card

You manifest a playing card made of arcane energy and hurl it towards a creature in range. Make a ranged spell attack against the target. On a hit, it takes 1d8 damage. If the hit is a critical hit, the creature takes an additional 1d8 damage.  Each time you cast this spell, roll a d4. Whichever number the d4 lands on, you must change the damage type of the attack accordingly. 1=Fire, 2=Ice, 3=Lightning, 4=Acid
