Hey guys, I'm making a rain team because well, because I can, and I wanna know what are so good options to fill my team slot.

Sp.A Politoed with Drizzle.
Helioisk
Machamp

I need three more members, I'm considering a Bulky Goodra with Rain Dance or maybe a Klefki with Rain dance.

I also was considering Noivern because it can learn Hurricane and its fast as fuck, and later on when Pokebank comes out, I want to throw my Feraligatr in there because he's my favorite starter.

However until then, what members should I have? Is Mega Blasotoise any good? It would be nice to use a mega pokemon, I like the gimmick.
