Lets face it guys please... He is a premium ninja with 20k coupons that normally goes with at least another support with 20k coupons too.

If you put it like this, then if you have a 2*20k coupons ninjas you could manage to beat him.

Don't complain about him when you are a f2p that use normal ninjas or outdated premium ninjas that cant beat him.

he is good and pretty much good actually for 20k but he is not a God. if you have well stacked minato and 5k madara you can beat him

if you have konan and anbu yamato and fire main you c*so beat him. but you need to invest in ninjas to be able to beat a premium ninja.

Personally I face him in any given day with opponents same as my bp and still manage to kill him. just focus to kill the other 3 ninjas and don't waste your mystery on him in the first 2 rounds (only chases attacks that he suffer is enough) then on round 3 when all his team is dead you can kill him very easy. but ofc you will need to invest wisely to be able to do that.
