What the? RUUUN!

They really should give this thing Gunk Shot, because Flash Cannon really isn't cutting it.

Is Iron Tail not good enough?

Its special attack is higher than its physical attack... then again, gardevoir has awful physical defense even when mega evolved, that, coupled with iron tails higher BP means gardevoir would probably be ohkoed by iron tail over flash cannon.

252+ Atk Hydreigon Iron Tail vs. 252 HP / 252+ Def Mega Gardevoir: 194-230 (57 - 67.6%) -- guaranteed 2HKO

But, who the fuck play a 252/252 bold M-Gardevoir, lets be more realistic:

252+ Atk Hydreigon Iron Tail vs. 4 HP / 0 Def Mega Gardevoir: 294-346 (105.7 - 124.4%) -- guaranteed OHKO

Yup, it still a terrible idea to play physical Hydreigon, but in this case it could work.
