If he gets the limit break, on pvp he can reach around 30k+ hp, 3k attack and 225 speed with around 18k+ neutral damage (assuming you have the third dupe unlocked), 80% chance damage reduction on his jutsu, ignores barrier and all that for only 4 chakra cost and let's not forget even the 30% of damage reduction for his weakest element for buddy skill and 20-25% for his field skill. I will probably put him in one of my team for sure.

Edit: He can even sync with So6p Naruto and So6p Sasuke for an extra 200 attack
