The way im seeing your team
You need a reliable counter against ground types. I agree that you should replace Fracture, because of his low speed and his deemed bulk. Elektross would deal alot to Dodrio, since that dodrio is weak to electrics. Plus that levitate will come handy in incomming earthquakes so which is nice. Well you should replace you seismitoad because, Golduck would make a fantastic sweeper with its awesome special movepool!
