I played that scenario, and, to be honest, it got me thinking of how you can make Indian better, and more compatible with Magitech. But I will not talk about that here; I could start a new topic, but only if you'll be an active part in it Titi. I do not wish to be "talking" to nothing. And if you don't want help, I understand that too.
I lost several times with that scenario, though. My basic stategy is defence until right after a big attack by team "A", then I build 16 (because that's the max movable at one time) of the strongest unit (in this case Thunderbird) and because Team "A" just attacked me, he probably doesn't have much fighting units left, so I can defend without losing any offence. Then I attack with 16, and believe me: no Magitech faction played by a CPU (except maybe Dark Magic because of the Fury of the Tiki) can withstand 16 of the strongest of any faction.
