Zeta's Sandstorm Team (in the works)

First off, if this is in the wrong section, let me know...

I've been working on a Sandstorm team for a bit now, and I have a pretty good idea of what I want to include. I intend to use this for both the Battle Subway (Double Battles) and possibly the PWT. So far, I have these prepared:


Hippowdon (still training)
Ability: Sand Stream
Nature: Brave
Moveset: Earthquake, Stone Edge, Crunch (to be replaced with Ice Fang), Slack Off

Landorus (still training)
Ability: Sand Force
Nature: Naughty
Moveset: Earthquake, Stone Edge, Brick Break (will replace with U-Turn once acquired), Bulk Up

Excadrill Lv. 85
Ability: Sand Rush
Nature: Adamant
Moveset: Drill Run, Iron Head, X-Scissor, Sandstorm (as backup)

Gliscor Lv. 85
Ability: Sand Veil
Nature: Jolly
Moveset: Earthquake, Acrobatics, Stone Edge, undecided move

I'm working on getting a Ferrothorn as a possible wall and to counter Water-types, as well as a Spike layer. I was considering adding Shuckle because of it's walling abilities as well as access to Stealth Rock. Shuckle also isn't deathly afraid of Fire. A mixed Lucario set could be viable. Metagross could replace Landorus if I wanted to. I could also run a Sand Rush Stoutland for some variation...

All I'm looking for is a little feedback. Would what I have prepared be useful in the Battle Subway and/or the PWT? What could I add or replace?

 

My main problem is that I don't have access to a lot of the items that would make this team stand out. I don't have any Choice items, a Life Orb, or... well, anything else you've listed. I'm still scrounging around for a Flying Gem for Gliscor. I can give Landorus an Expert Belt. Hippowdon may have Leftovers, seeing as it's built like a tank and soak up physical attacks.
I can replace Excadrill or Gliscor with any of these:

Nature: Quirky
Ability: Iron Fist
Moveset: Shadow Punch, Earthquake, Drain Punch, Ice Punch

Nature: Impish
Ability: Intimidate
Moveset: Earthquake, Crunch, Stone Edge, Outrage (may change)

Nature: Lax
Ability: Clear Body
Moveset: Meteor Mash, Zen Headbutt, Earthquake, Hammer Arm (may switch for Magnet Rise)

Again, these are just what I have on-hand. I can easily get an Adamant Golurk or Moxie Krookodile.
