Help Me Finish My Team

I am in quite a predicament. I have 4 members of my 6-Pokemon team solved out.
I don't have any exact numbers, but i can tell you which stats are EV trained the heaviest.

Empoleon- defense and special attack - balanced between various roles- Steel/Water
Abomasnow- defense and special defense- staller - Grass/Ice
Snorlax- defense and special defense- absolute wall- Normal
Hippowdon- defense and special defense- physical wall/staller

Now,
There are four pokemon I am considering in specific combinations to add. The combinations are:
1.Gardevoir (speed and defense- balanced between various roles-Psychic) with a Gallade (Attack and Speed)
2.Gallade (same as above) with a Walrein (special defense and defense-general wall- water/ice)
3. Gardevoir (same as above) with a Lucario (sp. attack OR attack and speed- sweeper)
4. Gardevoir and Walrein, both are the same as above.

Any general suggestions are welcomed, and I simply ask that any criticism be constructive. Quick replies are appreciated.

Your team has not synergy, u should pick or a hail team or a SandStrom team, because hail and storm on the same team doenst work.

If u want some good try to make this : Tyratnitar, Hippodoom, Gliscor, and 3 more that doens´t lose to much life,

My choice would DEFINITELY be the third choice.

Easier to explain if given moveset, but...

Your previous thread was already moved to the Request a Moveset / Simple Q&A sticky. Incomplete teams should be posted there, as stated by the rules.
