If your thinking on awakening old and weak Eddies, i think the next ones could be:
- Seventh Son Eddie: this poor guy is useless, it only "works" with the newest or most powerfull talismans and he still dies really fast
- Alexander Eddie: still a good Eddie, but he's lacking of offensive and defensive power
- Hallowed Eddie: same as Alexander Eddie, good but kinda weak on this days
- Wickerman Eddie/Shadow Wickerman Eddie: both are useless even in the lowest levels of the story or pvp, so they should have an update on their habilities. Also Wickerman Edd needs a re-design, he's pretty bad looking compare to his pasive version

And for the allies could be Necropolis, Killer Prime or Set: all of them are good in some cases, but they are a little outdated... maybe excepting Necropolis, who still defends pretty well, but the other two are really week in most of the battles
