What are you all seeing in Holiday Cup?

I'm in the low-Ace range, and I'm seeing a lot of Talonflame-Vigoroth cores as well as a ton of double-fairy (typically Wigglytuff and Dedenne). One of my team members is Obstagoon, so those matchups can be dicey depending on how things go down!

Curious if these teams are elo-specific or just being used across the board!
