Tsukiyomi yes, its only been done to single characters at at time, but Amaretsu worthless against large groups, why? Only 2 have shown abilites vs. Susanno's and Amaretsu, Gaara, and Mei, the other 3 Kages have not shown the ability to stop either. Tsunade has no defense at all but to call on others, Oonki is more worn out than anyone on the entire Alliance side even with a quick heal from Tits Malone, and Raichu has only been able to run away from Amartsu's users line of sight, but he couldn't stop Sasuke by himself and as KYF said I must agree, Edo-Madara has done nothing seriously or with strategy. So what he can ultimately do JUST LIKE SASUKE is unknown, at best somebody can pull a guess from past battles, but besides Tobi vs. Konan, no EMS user has been seen going all out to the death vs anyone, so to 'know' what they can do is an impossibility.
