Help Fairy Killers

[Dennis]

Need some advice for a Gardevoir GX killer. Faced it in PTCGO and wow.
Was thinking a possible Metagross GX with ??.
Any possible suggestions or ideas ?

Metagross does the trick. I play Solgaleo-GX Genesec-EX, fairy decks usualy quit when they see the sunburst GX

Metagross is going to be strong next format and has amazing match up to Gard. If your local meta is heavy Gard then you should sweep locals with Metagross. Also Garb variant utilizing garbotoxin can be effective.
