Here is a great tierlist by Dysole, use pods built around common squads in the high tiers and you will be fine.

But basically just limit the number of diffferent cards to put OMs on (1 or 2 max) and you'll be fine. Pod draft isn't much about army building, it's more about drafting the right pods, so you have to know how the pods machups vs each other even those from your opponnent.
Example of a quad pod in your tournament format:
- 3xPhantoms Knights, Siiv 250 points 10 figures
- Nilfheim 1xGreenscales Isamu 250 points 5 figures
- 2x10th Reg, Kravs 250 points 9 figures
- 2x Dwarves, Ulfrid Wornhangler 250 points 9 figures
Here I went for very strong pods but you can go with weaker pods with figures lower in the tiers because you can pick opponnent pods if you want to.
But if you're not familiar with all the figures I suggest you to build strong pods so yours will be used more. If you just want to have fun and use many figures, or if you feel confident playing figures you don't know, then you can play weaker pods.
