fairy deck?

[SmellyCharzard]

any suggestions on supporter cards too have that will support fairy types?

Hmm. Well for starters, there's Diantha. I've also heard prism star Xerneas and Geomancy Xerneas is good too.

Go to Collection > Trainer cards.

 

Check also "Show not owned".

 

Type "Fairy" in the search box. There you go, all the trainer cards related specifically with Fairy.

 

Additionally, set filters for Standard, Expanded, Item, Stadium, Expansion, Attributes and so.

The only supporters are Diantha and Mina, though there are some other trainers and some good ability pokemon.

Don’t know about supporters but a good stadium card that I have in my physical Pokémon card collection is fairy garden. Allows you to retreat any Pokémon with fairy energy attached to them for free. May already be a popular card that you know about and I may just be pointing out the obvious (sorry if so) or maybe it’s no good anymore.

Hope this helps!
