This is a combo of trick room and sand storm. first up Tyranitar(crunch, earthquake, stone edge, swords dance) to set up the sand storm. Then I switch to claydol to set up trick room. and then
Rhyperior(the tank-wall-sweeper) rhyperior gets a S.def boost from the sand storm making him pretty much invinceable, earthquake, stone edge, curse, megahorn
Rampardos(the sweeper) earthquake, stone edge, Thunder punch, super power
Aggron(the same as perior) earthquake, stone edge, iron head, ice punch
Lucario(for when trick room wares off) Aura sphere, psychic, dragon pulse, nasty plot
