I'm ok with going for a better Grass type pokemon(Unless it has a legendary status). I would like to keep Dragonite so I don't have a problem with getting rid of Tyranitar. I know it wont be a Sandstorm team, but that is why a had a ? in my topic title. I figured 4 out of 6 of my pokemon wont be harmed by it so I might be ok.
DW Cradily - Storm drain cripples most water types that don't pack some form of Bug/Fighting coverage. Plus with a tutored Giga drain, it can force out a good few water types what with its massive special bulk which is boosted in the rain. Stockpile or amnesia(iirc) can boost this further.
Gastrodon - Again storm drain, though i wouldn't use this guy with Swampert, very bad with both sharing a 4X weakness (albeit to an uncommon type)
Scizor - Immunity to sandstorm and heck band it and let it wreck havoc with bullet punch before it goes down.
Aggron - Only particularly noteworthy in trickstorm teams. Sturdy allows it to come in on the switch in trick room, but otherwise it is too slow.
Gengar - A painsplit-gar can work to your advantage, as the residual damage from sandstorm works to make sure you can siphon the enemies health. If you need a guarenteed KO. Destiny bond is a nice way of doing a 1 for 1 tradeoff.
DW Alakazam - Magic guard means you no longer fear sandstorm. Give it a focus sash, if you want to ensure two hits against bulkier pokes which can OHKO. Or give it a life orb for no recoil and massive power to OHKO most targets.
Reuniclus - Trickstorm. Quite slow but does have nice bulk to back it up.
Armaldo - mentioned in the post above. Has access to rapid spin too!
there are others but these are some pokes which do well in sand.
