Kabuto/Jigokudo/Tsunade sannin war/Cee/tsunade hokage, Sailor sakura, Han, Azure fang. That team can't withstand triple healers and poison. Yes, for swb is not a good team since is slow but let you win for sure.

Another team you c*e is the new one we got since you use mb: ay 3rd, samui, omoi/darui.

Both of them are f2p

The first application yes, but very likely you'll heal it or if goes to roshi is no problem, but the other 3 ninjas will be affect by it. In round 2 and 3 you heal and you use roshi or han mystery on masked man after he avoids sailor sakura or roshi standard. Round 4 masked man is dead and without masked man that team dies. If the enemy uses 4th sb mystery then you just wait to use han cleaning after he uses it. And you kill masked man in round 5-6.
