In Battle Team menu, you can see which agents are assigned for each team preset.

Agents who sit around table are the ones who are already assigned to the team. The list on the right side of screen are the agents that you own.

If you click an assigned agent and click an agent on the right side list afterward, assigned agent will be switched.

If no agents are assigned to the team, you can assign agents by clicking the agents on the right side to the desired position.

Recommended can help you to assign agents with the highest combat power to the team automatically.

Arrows on the left and right side of Team A/B/C can switch the presets.
