Any particular thoughts on how to handle the diplomacy cards on this one? Any tips would be greatly appreciated. Always ends up with me and 1 AI going at it and he usually controls the majority of the board.

i didn't use any diplo card to beat that level.

Thanks Tim. I tried the level again without using any of the cards and defeated it. Don't like those cards at all.

The diplo card actually hurt me on this one since I didn't realize that AI in the top right corner started with a massive stack. I got worried about the middle right AI seemingly getting too strong so I diplo'ed the boss AI and the one to his left. I'd have been better off leaving them alone and letting them contain one another better.
