There is a difference between a voluntarily entered loop and an accidental one. Magic has lots of both, I'm hoping this game has lots of one and none of the other. From a coding perspective loops are to be avoided like the plague in things like this. You can and will crash the server... I've seen it happen.PS. In Magic if you enter an involuntary loop the game is a draw. For all other loops it's entirely about whether the player concedes or not. The Splinter Twin combo is known as the combo everyone knows but no one ever sees. The opponent always scoops if they can't stop the combo happening.
Out of curiosity, how is it possible to create an infinite loop with the current cards. I think the fact you have to exhaust a card to play ability, prevents voluntary loops as you cannot play the same ability again.
Scooby stop trolling Kira in the forums. If you have a problem with how he converses with other people take it up with him in a PM.
