Move Dragon Claw to Moves, or even remove it completely. It doesn't deal with the Pokemon that wall your first two moves (other than Goodra), and you don't really need a reliable move outside of rain, as this set is meant to be played in rain. If the situation really calls for it, 70% accuracy is fine anyway.
Also, i would slash Extremespeed before Roost, as its a great tool to finish off faster foes that try to switch into you, and a great revenge killing tool too. Roost is always nice, but strong priority that bypasses opposing priority and nabs many 2HKOes on faster foes when combined with one of the other moves is invaluable.
Finally, why enough Speed to outrun Breloom? It would never want to switch into you, or face you in a 1 v 1 scenario anyway. I think we agreed that you should just aim to outspeed min Speed Landorus-T. (outspeeding 16 Spe Tentacruel is speed creep).
