Help with building a formation for Tales of the Champions

I was wondering if anyone could help me build out my formation specifically for the Tales of the Champions quests. During on the variants, I actually got up to level 1250 but forgot to save my formation. It was one of the ones that had restrictions in place but I cannot remember which one.

Since that time, I am having difficulties getting to even level 600 again with the formations that I have been trying.

I have tried using the byteglow formation building, but it does not really tell you anything other than the modron core bonus. I thought it would for sure tell you how much the champs are being boosted by the other but i guess not.

I have attached a screenshot of the champs that I currently have. Any kind of direction would be most appreciated. Wish I would just have saved that formation ....
