THIS.. IS.. SANDY!

Generic topic title ftw!

Anyway here's the sandstorm team I'm making.. I'd like some advice:

Hippowdon- Impish - leftovers
252 hp - 4 atk - 252 def

-Earthquake
-Ice fang
-Stealth Rock
-Slack off

My supporting lead, sets up Stealth Rock and acitvates sandstorm. Can wall great and attack pretty good aswell.

Lucario - Adamant - Life orb - Inner focus
4hp - 252atk - 252 spe

-Close combat
-ExtremeSpeed
-Swords dance
-Crunch/Stone edge (not sure yet)

My sweeper, can kill quite a lot of the walls.

Forretress - Relaxed - Shed shell / leftovers
252 hp - 162 atk - 96 def

-Toxic spikes
-Earthquake
-Rapid spin
-Rest

My physical wall, with toxic support and rapid spin.

Tyranitar - Adamant - Choice band
60hp - 252 atk - 196 spe

-Crunch
-Stone edge
-Earthquake
-Ice beam

The green tyrant, need I say more?

I'm not sure about this one, but I need a special sweeper.

Magnezone - life orb..? - Mild - Magnet Pull
88hp - 88 atk - 248 spA - 84 spe

-Thunderbolt
-HP (Ice)
-Magnet rise
-Metal sound

I'm really not sure if this is a good spe. sweeper for my team...

And I also need a special wall, but I don't have one in mind yet.

Any and all tips are welcome.

To much fighting weakness, infernape walks all over your team lol, infernape is actually quite annoying now that i realize it. All sandstorm teams should have either a nape counter or a poke thats faster then nape. Options enclude Aerodactyl, maybe scarf heatran, um scarf chomp garchomp, but beware lots of napes carry hp ice now intead of grassknot so take all these things into consideration.

Yeah, Infernape would kill every pokemon on your team.

Is this a Sandstorm team? It looks like it...if it is maybe Cradily would work for a special wall.

Oke.. an infernape counter and yes, it's a sandstorm team. I'll look into Cradily, thanks!

Btw, do toxic spikes and Stealth rock stack or can you only have one at a time?

EDIT:
Cradily seems to be my best option for a Sp. wall and I think Starmie could be a pretty good counter for Infernape. But I'll have to get rid of one of my team, and I have no idea who..?

EDIT:EDIT:
I'm pretty sure that I'm going to replace Magnezone with this Starmie:

Starmie - timid - leftovers - Natural Cure
172hp - 120 SpA - 216 Spe or
4 hp - 252 Spe - 252 SpA
Not sure if it should be more bulky or more powerfull..

-Ice beam
-Recover
-Surf
-Thunderbolt

Yeah, defenetely go for starmie, go for the one with 172 hp, but instead id use.

164 hp, 132 sp.atk, 216 speed. Because some people tend to put extra sp.def on garchomp. and with sandviel you dont want to miss and attack and let garchomp survive.
and yeah toxic spikes and Stealth rock can stack
