It would be really helpful if you post your recruited ninjas.
Assuming you have most ninjas, you can try and use:
Samui, 4th Ay, 3rd Ay, LM - Samui mystery on minato to remove dodge,
LM iaido to tag and paralyze him, if enemy doesn't cleanse tag with kurenai, 4th ay will blitz him.

You can try and get Yagura to steal an auto barrier gaara.
You go switch to wind main + kurenai, flower guard and sand dust on enemy. The other 2 ninjas could be Roshi/Fuguki.
Roshi/Fuguki teams, esp with azure can help you melt down minato, as long as you wait till his dodge get triggered.
