[Eos Aduro]

Do I NEED a Special Wal for my WiFi team? Im using

Gardevoir
Gengar
Aerodactyl
Metagross
Omastar
And I want Tangrowth here, but do I absolutely NEED a Special Wall?

 

[Skelter]

alot of people say it would be very handy...buuuuuuut i never use any walls...i'm just not good with them....

You don't need one and Gardevoir wil help out in that departement but Its still highly recommended.

You may want one, some good ones are:Milotic, Blissey, Snorlax, Dusknoir
Dusk, Milo and Snor for offensive walls
Blissey for mega wall.
