Wild Card

You manifest a fragment of magical force in the shape of a playing card and hurl it at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d4 force damage. If you roll a 4 on the damage die, you can make another attack roll against the target as the card divides in mid-air. Each subsequent roll of the damage die causes an additional attack if it rolls a 4.
