Agreed. "OMG Lucario is the best check to Excadrill because of AIR BALLOON!" "Oops I accidentally got hit by a Volt Switch from a Forretress...and now my balloon is gone...fuck Excadrill!"
To beat Excadrill, you need counters like Gliscor and / or weather changers; balloon just doesn't cut it.
I don't necessarily agree. With team preview, you can see if the guy has a Excadrill at the beginning and plan accordingly. You can hide the Luke to from attacks and make sure he doesn't get hit.
Also, Excadrill's Rock Slide is not that strong at all. It definitely suffers from it. Stuff not weak to rock that fly can check it. The obvious ones are Skarm and Gliscor who wall it pretty easily, but a Landorus can also take a +2 Rock Slide.
Here is a Calc for 252 Atk Excadrill with an SD Boost against 4 Def Landorus.
810 Atk vs 217 Def & 319 HP (75 Base Power): 201 - 237 (63.01% - 74.29%)
Here is a Calc for 252 Atk Excadrill with an SD Boost against 252 Hp Latias.
810 Atk vs 216 Def & 364 HP (75 Base Power): 202 - 238 (55.49% - 65.38%)
Latias can then use Surf or Hidden Power Fire to finish the Excadrill.
And these calculations assume the Excadrill uses SD on the switch, which most of the time it doesn't. Usually when an Excadrill is sent in it doesn't even use SD unless it comes in on a resisted choice move or something. If it uses Earthquake on the switch. Latias and Landorus can even set up...
