Event Details
In the next game update, LW will finally introduce unit supports based by attribute. Separate from your team layouts, you can set a leader for each energy type with Edit Support menu option. From here, you can set any unit under the first option: FREE, followed by one each of the main energy types. The last option is the "Special" frame aimed for 
INFERNAL and 
VALIANT energies. There's no costs using this option, as these are units for other players to use. Additionally, the top of the frames change patterns based on card rarities (implementation of this feature is planned for other unit frames).
