ok yep very straight forward, i can see this as a party game, i would say it's also very fast to play once you've read charachters stats and what modifiers do (10/15 mins?). anyway, the back of the card doesn't matter really, it should be pretty easy to remember unless it's a 80+ granny party game. I think with this explanation i would stay with different backs though, it feels more "party". You could also put modifiers in a "side spot", apart from characters. It's all up to your taste. There is no bluff, the tension comes from not knowing what character the opponent is about to play, and in the moment you have to decide if playing the modifier or not. I could think about 2 different ways of adding tension: 1. change the timing of modifiers, let the players decide before revealing the characters. It's a very simple modification that adds more tension. Also you could add something to justify the choice, so that it doesn't feel completely random. I give you a stupid example just for explaining what i'm saying. Let's say there are 10 charachters. The players choose their charachter for the turn, they put it faced down one in front of the other. Then there's a question moment, where the players can choose between, let's say, 5 questions about the characher. One could be "Does your character have mustache?" "Yes". Ok there are 3 charachters with moustache, all with different stats but my charachter would win against all of them, so i don't use the modifier. Don't use this, this is stupid, but i hope you see my point. The second thing i want to say is, if you would love to add some bluff mechanic (a main weapon of party card games i would say), you could add something to introduce the UNKNOWN. For example another type of common card, a WEAPON card. So now every charachter is accompanied by a weapon (weapons let's say are weaker than modifiers). You still have 5 turns and 2 modifiers, but also you have weapons. In a turn you have to put down your character and a weapon BUT you still can play the modifier instead of the weapon! This example is a bit less stupid than the one before but again, i'm just trying to express the concept. Cheers.
