Yuka vs Dabura...

Okay, Yuka either losses or draws against Dabura, right? Yuka has access to Rika (assuming Tsurugi gives her the ring), Mahoraga (If she has 10 Shadows), and a 9 Shadow Agito (also if she has 10 Shadows). This makes the fight against Dabura a 3v1 if she tames Mahoraga. This means it's a 2v1 if Yuka isn't suicidal during the fight and a 2v1v1 if she is. But if she gets Yuji to help her tame Mahoraga, it's that desired 3v1. But if we use the excuse of Yuji helping Yuka, we can say Yuji trained Yuka to be at least a grade 1 sorcerer. Which this, it could be considered a 4v1. And then just maybe Yuka will win against Dabura.
