Good team Shadow. A few tweaks here and there and youll be all set.Sandstorm team V2!
Tyranitar / Adament
Lovin the TTar. Obviously this is your lead correct? Only thing I might change is have a different poke for a lead, speedy anti lead who can set up stealth rock, prefferably Aerodactyl. SR would benefit this team alot... Not to mention TTar could get pummled by more common leads... Maybe infernape close combat or even Scizor could destroy him with Superpower. Other than that, I love this TTar. Only thing I would change is Adamant to Jolly. That bit of speed could make or break the Metagame.
Swampert / Adament
Nice Pert. Straightforward... But your not using set up Cursepert with this? He has room to shine... And I understand, like me, you seem to not like using Stat up sweepers prefering to go straight for coverage... But working Curse and Leftovers in a sandstorm in place of BB could be more beneficial than this set. Also, whats Ice Pinch? lol. Doesnt hurt as much as the punch? lol.
Lucario / Adament
I hate lucario... Im not giving much an opinion on this simply because I hate the poke. The moveset looks nice, but again, I would use a Jolly nature with a LO to maximize speed and power. Unless your using CB, in which case I would still recommend Jolly.
Metagross / Adament
Ah but where is Bullet Punch for revenge kill on that monsters attack stat? lol. You have agility to make up for it, so its all good. But Bronzong will wall his ass badly using Psychic and Steel as a combination of attacking moves. Maybe make use of his Elemental punches and you could even throuw an EQ in there if you wanted to.
Flygon / Modest
-Flamethrower or Fire Blast(not sure)
I love Flygon. Great poke. great dragon... Shines tremendously in OU thanks to sandstorm teams. if your looking for a fourth move... Signal beam could prove helpful. either that, or give him sandstorm in case something breaks the SS before that.
Scizor / Adament
Scizor is a beast. This is great just the way it is... Maybe replace X scizzor with U turn if you want to scout.
