Fair enough. Goku should handle Ciel then. I think he can pull it off after a long and tough battle.
Don't forget Ciel has the Mystic Eyes of Whisper that would allow her to hypnotize those in eye sight of her. With exception to Erza, the rest of your team would be vulnerable to it and Ciel could use the Eyes to turn your teammates against one another.
Now for Priscilla I think Ichigo will have trouble, but Goku could use the remaining energy he has and help him defeat Priscilla, but it will be tough
Priscilla's speed is the major issue for Ichigo in a confrontation between the two, as she is greatly faster than him. Goku might be able to assist with ki attacks on the ground, but being grounded will make getting an accurate shot quite difficult.
That leaves Rider vs Erza. Erza needs help from Moka and Shana, and a good Fuzetsu and attacks from Shana weaken her, giving Erza and Moka to finish her off.
Fuzetsu's not gonna effect Rider since she's a being made from magic and Shana's presence is only gonna add more magic for Rider to feed off of to increase her power while Blood Fort's active. Moka's still gonna be a non-factor here.
Solty then faces Luffy and Charizard and while I agree Charizard might get taken out, he contributes just enough for Luffy to get the win.
I doubt Charizard's gonna contribute much here thanks to being slower than Solty. Don't forget that I can exploit the island setting to have any of my team members submerge him into water.
Chise is left and she will get ganged up on by Erza, Ichigo, Shana, and Luffy. Shana uses the last of her energy for a Fuzetsu and weakens her a bit until she exhausts herself.
Shana gets picked off by laser fire before she can bother and nuking will commence then in this scenario.
This might seem like a bold statement to make (and I don't mean any disrespect saying it). But with exception to possibly Goku (who'd have a hard enough time connecting with attacks thanks to inability to fly), your team's not gonna have the destructive power to take out Chise and Solty, as both have tanked city-scale destructive power (Chise via her nuking, Solty with the mentioned space station explosion).
