Heres MY suggestion (its ok if you disagree)
Metagross-Having Bulk, it is postive to take opponents down.
Meteor Mash, Agility, Earthquake, and Physhock
Dragonite- Great Pokemon, HARD hitter
Dragon dance, Outrage, Earthquake/Fire Blast, Draco Meteor
Lucario(Physical set) Great Speed, Great power
Swords Dance, Extremespeed, Close Combat, Fire/Ice/Thunderpunch
Weavile-Cold Evil! :D
Swords Dance, Ice Shard, Ice Punch, Night Slash
Great Offensive team here
Hope I helped!
