Now way back yonder in the 90's a card game came out called: Magic the Gathering, it is in the line of the Pokemon card game or Yugioh(well maybe not Yugioh, I think you can just play cards period regardless of mana costs in Yugioh), you buy a started deck(usually about 30 to 50 cards), a few booster decks(around 15 cards per pack), you arrange the best cards you find into some semblance of a fighting deck depending on what creatures you have. Many I day did I spend playing this game, Magic is slightly different than other card games in that it is built with a potential cooperative mode from the start. Magic uses 5 different "magic types" white, black, red, green, and blue, if you look at the back of a card the line up in a pentagram pattern:
Like so, and per the old rules who ever was diagonal from you was your enemy(so for white it was red and black, for green blue and black and vice versa) and directly next to you was your friend. Now some of you might be looking and saying, "wait what, but that means both of your allies are also allies with one of your enemies!" yes, yes they are. Which makes for an interesting bit of diplomacy, because sooner or later you are gonna want to go for a kill shot and are going to have to make a request. for black to win white and green have to die, for red to win blue and white, and so on and so forth.
