So, I'd like to build a well-balanced team that can earn me 200 straight wins in the Battle Maison. Only problem is, I suck at building teams. I can never seem to find a good balance.

So, does anyone who has managed to make very significant progress have any suggestions? Remember, all of the major Legendary Pokemon, meaning Mewtwo, Lugia, Ho-Oh, Kyogre, Groudon, Rayquaza, Deoxys, Dialga, Palkia, Giratina, Reshiram, Zekrom, Kyurem, Xerneas, Yveltal, and Zygarde, and all of the event Legendary Pokemon, meaning Mew, Celebi, Jirachi, Phione, Manaphy, Darkrai, Shaymin, Arceus, Victini, Keldeo, Meloetta, Genesect, and Diancie, are banned from battling in there.

So, with that in mind, can anyone think of a well-balanced team that would allow me to keep winning in any of the available formats?
