Interesting card. Lots of damage boosting cards exist and it has synergy with Max Potion. I'm sure it won't see play!
Mina and Xerneas BREAK perhaps?!Ribombee I guess is effectively the anti-Guzma for Fairy. Potentially important? I dunno. Seems like a clunky tech.
Mina seems a bit underwhelming when Gardevoir GX is currently the strongest Fairy attacker. I would rather play Lady and Secret Spring. I guess it's decent energy acceleration for anything not Gardevoir GX.
Actually, that might be good in expanded, a xerneas break deck with Mina, fairy garden, xerneas prism and xerneas gxMina and Xerneas BREAK perhaps?!
