Do not use that team. Since you own ay 4th means is sure you own also darui. Use darui ay 3rd samui with earth main or use darui ay 4th samui with lightning main.

If you want to keep going on with the subpar version you run now then is mandatory that you boost to max ay 4th otherwise you have no hopes to nuke anything in round 1. Round 2 ay 3rd gets the boost from chakra that is more than enough.
