Foreword
All those built teams assume characters will be at Tier 3. Also BP and Gacha EGO are not included in Affinity calculations.
Always use base Identities after you clear chapter 2 for their passives unless you have other Identities at Tier 3. Also, those are just examples of teams. Do not take those as granted as Limbus is a gacha. Adjust if needed.
Whale team

About the team
Can use any Base EGO available, may struggle a bit with Wrath EGO usage, but everything else will be easy to get. Most of the passives in this team also will be activated in long fights. In short ones, some will be used more often like W Corp Don passive.

Base Identities after Chapter 2 are promoted to Tier 3 for free meaning this team that focuses on supporting Hong Lu and his EGO usage can work. Any other EGO can be also used in this setup, especially Outis EGO.

About the team
G-Corp Outis and Gregor as a core. Those two work very well each other and with other characters feeding Outis her EGO requirements, it is easy to spam her’s and Gregor’s EGO often

3 - 2

About the team
This team will never use Yi Sang’s EGO which is not a big deal. He is there to mainly feed SIN affinities to others. Rodion Outis and Gregor are main EGO spammers while Hong Lu is sweeping floor with Cloud Cutter.
