@Guardian Angel Haruki Voth has proficiency with playing cards. What stat would be rolled to go alongside that proficiency? I could see charisma, but is it more important to have a good poker face, or to be able to read other people's poker face?
Also, Voth has a deck of playing cards. I would like to state for the record now that they are marked in a manner he is familiar with, as he has owned them for a long time, but he himself did not actually put on the cards.
It depends on what Voth wants to do with the playing cards...
If Voth wants to understand the rules of a card game, calculate odds, or spot a cheater, that would be an Intelligence check.
If Voth wants to bluff, intimidate, influence a player, or keep a poker face during a game, that would be a Charisma check.
If Voth wants to cheat in a card game by swapping cards or hiding them, that would be a Dexterity (Sleight of Hand) check.
Marked cards would help Voth with identifying cards and thus identifying if someone is cheating, or if someone is keeping a poker face.
However, marked cards do count as cheating before a game. So, for having your cards marked, I would like a retroactive Sleight of Hand check with your playing cards proficiency to see how discreet those marks are.
