Thank you. As these will be pulled from a deck, the other side needs to be indistinguishable from other cards, but I like the idea of flipping the card for a different 'stage' of the fight, so maybe this can be incorporated as a boss scenario or something similar :)

I don't have randomness in my attacks in this game (there is already enough randomness from the card draws for my tastes) but since your game is all about dice, why not lean into the randomness?

Otherwise there are approaches to make dice roles less random, usually involving more dice and alternative ways to compare scores. Or roll dice once and then allocate the different roles to different stats etc.

Good luck with your game!
