There are many counter to that team, the point here is to use strong burst team to take them out in one turn.
First there is the basic lightning armor blitz team.
Then we have the lightning 2nd round blitz with darui, iruka, naruto sage/asuma wb and lightning first mystery. Use lightning and iruka mystery at the end of round 1 should take out at least 50% HP of one of their ninja, then second round burst from darui at order 1 should finish the job.
You c*so use Hashi who not only have 2 stun per round but also the strongest damage buffer in the game right now.
And the most simple answer iiiiiiiiis
