New factions?

[Conqueror]

1: Numidia (Western part)
2: Veneti
3: Caucasian Iberia
4: A Celtiberian tribe
5: Ulaid or Erain
6: Remanents of the Scythians
7: Belgi
8: Northern part of the Mauryan Empire
9: Illyrian tribe
10: A German Tribe

Keep in mind that these (not just some but all of them) should be both:

1. more powerful/influential than Pergamon at their peak during the timeframe and
2. with enough information available on them to be feasibly represented as factions,

in order to justify giving Pergamon the boot (going by Foytaz's argument that Pergamon wasn't significant enough to deserve a place in EBII).
