if you want a wall I would suggest whimsicot instead of umbreon. Sub, seed, sday, and either toxic or encore. I would also suggest Darmanitan, flame charge is beast under the sun plus rock slide can counter pelliper. Another good sweeper I would suggest would be Chandelure. You do want stealth rocks on torkoal, the added hazards help.
I started running a s.day team after I caught a shiny torkoal that was decent. Its Torkoal, Whimsicot, Dramanitan, Chandelure, hydreigon, Volcarona, and it's done pretty good for me.
