Not a big issue at all, but something to improve compatibility with other mods.

In the Card:is_suit() hook, the line if self.ability.effect == 'Stone Card' or self.config.center.no_suit then should use SMODS.has_no_suit() instead for better mod compatibility. Less important, but if (self.ability.name == 'Wild Card' or self.config.center.any_suit) and not self.debuff then could use SMODS.has_any_suit for the same reason.

Right now this only works with enhancements that make a card have no suit, not other effect that do so, like from jokers.
Sorry if there's a specific reason this method wasn't used and i missed that.

As i said, not a big deal but I hope this gets changed, especially because it's a very easy fix
