Competitive Pokemon continues to be a joke, lol.

Welp, time to make a team of 6 Articuno with Mind Reader and Sheer Cold.
 
Try hitting me once with Mind Reader after I've Double Teamed 50 times with my Moody Bidoof.
 
So my planned party is:

1. Swampert
2. Sableye
3. Altaria
4. Metagross
5. Manectric

Any suggestions for my 6th pokemon? I'm thinking Ludicolo, Shedninja, Zangoose or Slaking. My team is more or less built to take on Steven't Steven's Metagross.
 
Ludicolo is pretty good, great typing, and mostly all around good pokemon.

Not to mention great abilities.

Zangoose can be good but the thing is very frail and without toxic boost its very hard to use, since it wont have time to use sword dance since its defenses suck so bad. Good physical attacker but yeah.

As good as slakings stats and movepool is, it has a hard time keeping up thanks to its crap ability.

It has some good moves, but yeah.
