Kalisto
I like Kalisto a lot. It’s always good to have an exciting high flyer on your roster. The first step is getting away from Sin Cara. The Lucha Dragons seemed to have lost buzz with fans since they debuted on the main roster the night after WrestleMania 31.
When it comes to in-ring work, Kalisto is better than Rey Mysterio in my opinion. If they let him have a singles run while booking him like a threat, he might get fans behind him. He is someone who I would build my mid-card division around. He has tons of room to improve, especially on the microphone.
Agreed to your point on Emma. She could be a big time heel up on the main roster. Imagine matches between her and Sasha.
They would be epic. There’s more attitude in Emma than we have seen. Hopefully she gets a chance to show it.
