Daily Punch 9-18-26 Dead Man’s Hand Rapscallion power for Pirate Borg

My players LOVE drawing cards and seeing what happens. Lets do that for damage!

Dead Man’s Hand

When you deal damage, you may draw a card.
9+: Deal additional damage equal to the card number – 8. Jacks are 11, queen is 12, king is 13, and an ace is 14. If you draw a joker, deal all the damage to yourself!
If taken again: lower the card number needed to deal extra damage by 1.
