I've been thinking of using this combo for several days now. The only problem is that Ninjask doesn't hold up well against Scarfers while in Advance he could outspeed everything. The good part is though that both Cradily and Octillery benefited from this new gen. Octillery gained Physical attacks to use in tandem with Jask's Sword Dances (Waterfall,Gunk Shot...). So the question is...how usable is it in today's metagame with the ability of resisting Roar/Whirlwind?
