This idea assumes you have a pretender with S4, D1 and/or A5.

An idea for the Pythium mid-game could be to aim for conjuration 6 and cast Ether gate. Expensive gemwise, but yields 15 hard to kill Ether Warriors. and a DDSSSS commander that besides being a good combat mage is definately SC material.

After this go for Conjuration 7 and put the air gems to good use in summoning the Queens of elemental air. These are fine SCs in my experience. But it might be a race to get these first. You might need to convert some gems to get them.

These should help you through the mid game
