Tartanians

That depends on how big the game is and how many experienced players are in them. Games on small maps with, say, 5-7 players never reach level 9 spells (or shouldn't, at any rate).

In a big game on a big map - if you really want to win you do need to think about late-game strategy right from the pretender design stage on.

A Tartarian factory is not the only viable late-game strategy, but as you can guess it is one of the strongest.
