I suspect that 3 mulligans per player may be a bit excessive, particularly if there's a lot of players... 15 playes at 3 mulligans per player would mean up to 45 turns when everyone would have to replay the turn.

Various ideas:
A. Reduce mulligans per player to 2 or 1.
B. Distribute mulligans gradually over time to surviving nations: say, start everyone with 1 mulligan, then give everyone still alive at turn 30 a 2nd mulligan, and a 3rd at turn 60.
C. Make mulligans fungible, allow trading of them with enforced honesty.
