Most powerful nation

[SelfishGene]

MA Ulm is a good candidate for the turmoil/luck trick since their troops cost so little (taking 3order/3prod with Ulm give you an almost unlimited supply of gold). Turmoil/luck provides hundreds of extra gems over the course of a game, and getting 30+ a turn is not uncommon.

Taking 2 Drain, 3 Prod, 3 Turmoil, 3 Luck, and making a powerful SC pretender with many paths, should cover most of your bases with Ulm.

I'm a fan of 9-Path Titan pretenders, but only when you're not sacrificing too much long-term magical diversity. Since Ulm's problem is almost by definintion magical diversity, your Pretender has to take up the slack, and there aren't any sacred troops to bother with anyway.
