The original post is from March, but I thought about how it would convert to The Black Hack.

Beat the Monster Rating, you go before the monster. Otherwise, you go after.

If you draw the same rank as the monster rating, Red suits go before the monster, black suits go after.

Drawing a joker means you roll with advantage and the damage goes up one die step.

Since TBH is player facing, no monsters or GMs draw cards. (Although a certain GM may draw from his/her own deck of cards for random encounters.)
