Once the hachibi starts firing off TBB barrages the summonings and the sannin dont stand a chance,,The Sannin take this.
Both Jiraiya and Orochimaru are no strangers to fighting Bijuu. By jiraiya summoning ma & pa and allowing them to summon Gamabunta, Gamahiro, and Gamaiken it allows them more then enough senjutsu power to restrain Gyuuki.
A and killer bee can use their double lariat that can and will behead tsunade and jiraiya,There is no damage that Ay could deliver to any of the sannin that Katsuyu couldn't heal the sannin from. They can easily come up with a plan to capture and/or seal the Raikage.

8-tails whirlwind is also a good way to repel off the summonings seeing how 3 of them were one-shotted by devas ST
A and killer bee can use their double lariat that can and will behead tsunade and jiraiya,
A is also much much faster than the sannin and can still use his lightning chops to pierce through tsunade and jiraiya,,
katsuyu being able to heal them isnt helpful once the sannin are dead,
only orochimaru is not being affected by A's attacks mainly due to him being extremely durable as well as his Oral Rebirth
Hachibi >> Shukaku,If I remember correctly Gamabunta alone was able to control Shukaku (1-tail) so 3 summonings are more than enough with Hachibi.
Also the swamp is available for the Hachibi.
--@Bold - Lolll,, Killer Bee is never getting taken out by Jiraiay and Tsunade, his DC is far too much for them to handle, regardless of jiraiyas SM or tsuandes byakugouAfter Killer bee is done by Jiraiya and Tsunade There isn't much A can do on his own cause the attacks won't affect on Orochimaru and Tsunade can heal Jiraiya and herself.And I think Jiraiyas reactions are good enough for dodging in the Sagemode,(In this scenario Sannins take this with mid/high-diff) but in the version without Sagemode (in the base mode) I think AB-combo could take this easily. with mid-diff.
