Mei Terumi. She have the most feats
Yagura barley have any feats besides in et.
Trollkage genjustu will nullfied by acid mist because mei doesn't necessarily need to locate it to destroy it. Also Trollkage won't have the chance on hitting her without melting. The main reason why he losses is because mei probably without a doubt have info on her predecessors. While he doesn't have none on her.
Well here's my take on that....the Genjutsu presents a multitude of illusions if it desires.this means Mei would have to attack all directions, and even then unknown distances. At the same time, Trollkage can simply move his clam...or of needed de-summon it..
Also, it was noted during his fight that information was kept right on Kirigakure as noted when some of his own village members knew hardly anything on him. So I'd venture limited knowledge.
Finally, Joukie Boy and the water fun....acid mist would ironically hasten the infinite explosion. Movement is what boils the oil, but if he charges into a steaming mist he'd practically explode instantly....he'd then cool down, but hear up just instantly.
During that, Trollkage just has to stay back and spam water bullets.
