Don't be like "omg icey get out you meanie" then mods warn me.
I played competitive back in B/W and X/Y so IK what to expect now.
The genies have scarfed lando paired with Air Balloon Heatran, Cresselia, Thundurus for Twave, Tornadus for Tailwind, or other pokemon that don't get hurt by EQ. Lando being scarfed KOs both Excadrill and Barb easy. (BTW Don't say like "Well I can get a Iron head off before they-" Nope because Landos are tanky as heck. Then Lando also runs Rock Slide. KOs Charizard with ease. Venasaur awesome pokemon but the problem being is Amoonguess Rage powder, Other Whimiscotts that are ran nearly same as you, and other supporter grass types are going to be noticed and Brave bird Tflame is coming for ya.
Facts on Whismicott: He needs Speed EVs so he can outspeed even a maxed out Thundurus and Tornadus. This being because it enables you to stop their status set ups.
So now the team is wiped by 2 obvious pokes and the set up left is vs a Choiced Hydreigon which are actually very nice.
Just Icey's thoughts
EDIT: I'm not expecting everyone to have the most key 100% solid team because I myself am in the same boat. Just sharing information that I learned from 2K+ battles that is really common that you don't want to have any of.
