I also advice checking out the official discord for fast strat help (as mentioned in the strat pinned post, forum won't cover as much):

Madara isn't benefiting from Masked Man or Itachi as supports. Recommend helping him out with chase increase (Hashi New Year, most if not all players have him) or Asura breakthrough if you have him. Additionally, while chakra battery isn't needed, nice control / chakra gain is Jiraiya Toads Chant (as mentioned by another).

Shisui Modern Asian style can be an okay support but don't recommend most other Shisui forms as they're outdated or would be a "better" position 1 / damager (like Shisui Susano'o four star breakthrough outclassing Madara himself).
