Enhance SBB's BB atk.

The selfish spark damage (that SP) is only better if said unit spark perfectly or is a nuker (Rize, Lauda, Silvie, etc.) which also need to be combined with a team buff.

Keep this in mind:

Team buff >>>>>> Selfish buff

This applies to everything, except nukers who are the only ones to take advantage of selfish buffs (combined with team buffs obviously).

Selfish buffs must only be choosed if you don't have anything else to choose or already have the buffs you need in your squad.
