With TWave already on Rotom-W, why not just use SD on Cobolian so it can actually do something (Taunt + SD is actually great vs. any stall team). I would use ChestoResto Rotom-W if only because it's better vs. stall and pain split doesn't really find as many uses (from personal expriences, yours may vary). Consider EQ over X-Scissor on Rak so you beat Toxicroak better (which kinda threatens almost everything if SD set... bar Zong ofc, but Bulk Up + DPunch would just murder you so I hope you consider taking precautions, especially since X-Scissor bataltly sucks on this team: switch to Zong for free SR on Lati twins .-.). I also would try to use Rest Zong, since it helps vs. Dragons immensely. Rest / SR / Toxic / Gyro or HP Ice is a great set since you can stall those Dragons out easily. The lack of rest on Zong worries me that your opponent can weaken it with stuff like U-turn and such.
