I doubt it would be useful to most players as FoGP is used to ramp evolutions and Aether Stadium only works on basic pokemon. However i think this card can make Raikou with shining body insanely good.
I run a very similar deck online and I would consider dropping the 3rd Yanmega break and instead put it a revitilizer, it will recover any lost pokemon and combos well will Ultraballs. Also cutting ultraballs to three and sticking know another Lysandre could save you from being locked by...
It is not a Basic Pokemon, it evolves from Fomantis just like and regular stage 1 Pokemon would evolve, so it's not that good. (with Forest of Giant Plants it can be a threat though).
I think the use of a Sceptile Ex 2-2 line would help to heal M Beedrill if he gets hit with an evolved Pokemon turn two. Also helps him recover energy lost from his attack.
