If you like Gothitelle, I recommend you should check this group out. It's dedicated to Gothitelle and her pre-evos, Gothita and Gothorita!
And yeah, I love Psychic-types in general as well as mainly Electric and Water-types as well.
Our Black teams are so similar - we both have a Hydreigon, Gothitelle, Chandelure and Samurott. I also used a Zebstrika at some point as well as having a Scraggy (she since evolved into Scrafty).
I also have a Beartic but I don't use her that much. Don't have an Escavalier yet but a Karrablast, I'll try and evolve him when my younger brother gets White.
The other two spots on my team are Archeops and Sawsbuck.
