I would say 5 Kage Madara since his ability to clear all buffs on the field really helps with supporting Edo Deidara who might get blitzed by Kushimaru or pos 1 LM teams. Chakra gain isn’t an issue as well since Madara can steal 20 with his chase which can be triggered twice each round. I’ve seen him work really well with Jonin Minato too when his bond mystery comes out.
