Season 0 was great.
However none of the games were actually fair. The Pharaoh chose games that the opponent was at an actual disadvantage despite an apparent advantage. The skill should reflect this.
The Pharaoh had to do thinking and preparing to make the situation work in his advantage though. Spanning all of the seasons though, it expands to "play game, loser of the game gets hurt" usually the game would be more complicated than a coin toss, but that would be hard to put into an EtG card. Would be funny though, if the card made you open a separate program to play another game to see who takes the damage... Really though, I just used it as a jumping off point. in true thematics, I would have focused on the "banishment" aspect and just have it act as CC, but that would be harder to balance and make interesting.
