SC Question

[incognito]

Been playing with a standard assortment of SC's in a SP game. Am around turn 50, so nothing really challenging them yet, which brings me to questions about their limits. For a standard outfitted ice devil, how will it fare against one or more of the standard high level summons? Tarrasques, abominations, tartarians, even vastnesses are all within the realm of the AI. Are different SC strategies called for here? Are higher level SC's going to fare better (eg Helio's, Arch Devil's, Banelords)?

A final question: one thread of answers might be around not letting your opponents get to the level where they can summon hordes of the above super summons. In a large game w/a large map, is that feasible? ie is there an end game strategy that so convincingly tips the game to one player that victory is all but assured (OK, clamming - there I said it)?

Thanks in advance for the thoughtful answers.
