Where to spent my diamonds on?

[Absolitetion]

I have not spent my diamonds yet, so far I have about 350 diamonds (I'm only Rank 9 at the moment I typed this).

What'd be the best thing to spent on with a diamonds currency early on in the game?

I'd say buy supports or decoration.
Piplup is extremely useful, Charizard also seems like a good choice!

^ supports are great. very expensive but a great use of diamonds.

If you don't want supports, Aegislash decoration is the best to get early on. It's really helpful when training.
