How or what pokemon should i use to make a untouchable Team.

I think your Pokemon Team looks very good. I would recommend adding Pancham/Pangoro to your Party. This will give you a strong Fighting Type Pokemon. However, this is completely up to you.

To answer your question: Yes, if your Pokemon has a higher speed than your opponent's Pokemon, it will go first.

Defense is always good to have. It allows your Pokemon to last longer in battle by taking more hits.

Hope this helps!

Another way you can make an UNTOUCHABLE TEAM for REAL is...

1) Wait for Pokémon Bank to come out and download the free thirty day trial

2) Make sure you have Pokémon Black 2 or White 2 or at least some game you can send to the Pokémon Bank...

3) Now you need to obtain a smartphone and download the app 'Pokecreator Lite' (this will allow you to make any Pokémon possible... Or impossible)

4) Make a team of unstoppable Pokémon by doing such things as combining the speed stat of a Pokémon and the ability 'No Guard' and a moveset of 1-hit KO moves such as fissure, sheer cold, guillotine...etc. To make it defeat anything (WATCH OUT FOR THE ABILITY 'STURDY' OR Pokemon THAT HAVE A NO EFFECT TYPE ADVANTAGE IF YOU USE THIS) or you can just create a strong Pokémon with strong moves and a high HP and give it the ability 'Wonder Guard' to make it undefeatable and top it off by giving it leftovers...

5) Now that you have your unstoppable team, follow the directions to send that Pokémon to your gen V game and once there, send it to the Pokémon Bank, from the Bank, send it to Pokémon X or y

6) CONGRATULATIONS, YOU NOW HAVE AN 'UNSTOPPABLE' TEAM...

NOTES: If for some reason it will not let you send it to the bank, check to make sure that 'legit mode' is enabled and try again...

NOTES CONT.: You can also use this to get more master balls by 1) checking the id number of the loto-id center in lumoise city and if you don't win, you should be able to try again but it will be the same number... Write this number down (digit for digit, all five have to be the same to make it give you a master ball) type this number in as the id number in pokecreator lite and repeat step 5 to send it to your game and then, once you have it in your game, go back to the loto-id center and ask again, if you didn't get anything earlier and you typed in all five digits correctly, it should give you the grand prize which is a master ball... OR 2) JUST GIVE THE Pokemon YOUR TRADING A MASTERBALL AND SEND IT OVER...

NOTES AGAIN: YOU CAN ALSO TRANFER OVER THE UNOBTAINABLE Pokemon AND EVEN LEGENDARIES ...

NOTES ONE MORE TIME: JUST KIDDING, BUT THANKS FOR READING ALL THIS AND FEEL FREE TO THUMBS UP THIS IF YOU LIKED IT... THANKS, AND GOOD LUCK WITH YOUR GAME

Well.. I recommend fennekin as your first starter Pokemon.. But there is another poemon from another region. After you have fought the doctor (or whatever he is), You can choose 3 pokemon. Bulbasaur or two others I have forgot the name of. I recommend bulbasaur since you can find a Venusaurite during the game, Bulbasaur evolves into Venusaur, so you can mega-evolve

Yes you have two steel types. However, special defense counts also because it will help you better defend from special moves, like flamethrower or thunderbolt. So I would suggest you have each Pokemon having two types different than the last like for example:

Steel/Ghost type
Fighting/Dark type
Fire/Flying type like Talonflame,since it's also fire type, ice types aren't supereffective, but Rock type is 4x the damage due to it being super effective against not only Fire types but also Flying types, so I'd watch out!
Psychic/Water type like Slowbro or Slowking...(Slowking has better defense) Slowbro has the opposite, which is attacking instead of defending. Its your choice, however.
Fairy/Normal type, now it's an extremely good idea because fighting types are no longer supereffective, they do just normal damage.
Ground/Rock type like Rhyperior which has very good attack stat.
I hope this helps, and remember I love helping people out.
