>Mega Gardevoir A+, Haxorus C-
I'd need to post a huge wall of calcs, but they would definitely show that Haxorus is just as big of a threat to stall as Mega Gardy imo. They say that Mega Gardy can easily wreck stall due to its massive power, access to Taunt and Calm Mind, and can even cripple some of its checks (Scizor) with WoW. Well, guess what? Haxorus also gets Taunt, has Mold Breaker to get past Mega Sableye's Magic Bounce, and boosts up faster with Swords Dance. It can also get past its own checks (Clefable, Sap Sipper Azumarill which does have its uses on stall) with Poison Jab, as well as outright OHKO Chansey with LO Superpower after rocks, without any boosts. I get it, Haxorus is kinda outclassed by other dragons, but it still has this niche. It also doesn't take the mega slot and is better against offense, since it takes priority attacks sans Ice Shard better (hell it can take a CB Brave Bird from Talon if at 100% health!).
But here's the most important part. I saw posts like this: "
More often that not, Mega Gardy doesn't even need any boost to screw with good portions of stall."
Meanwhile, from Haxorus's analysis:
"For pure wallbreaking purposes,
Swords Dance gives Haxorus the power it needs to be one hell of an anti-stall Pokemon."
In the same thread...
>Mega Gallade A+, Mega Medicham C+
"Against stall, Mega Medicham is useless because of Mega Sableye and Mega Slowbro, while
Mega Gallade 2HKOes Mega Slowbro at +2 and can even get past Mega Sableye with SubSD + Stone Edge or Skill Swap + SD, or even just beat Sableye with plain SD + SE, though Gallade will get burned in the process."
So I guess Mega Gallade outclasses Mega Medicham since it's a much stallbreaker, due to access to Knock Off and, get ready,
Swords Dance. While I can understand Knock Off, Swords Dance doesn't make it better against stall, really. Medicham doesn't need to set up, but Gallade really needs to.
With that said,
good job, Smogon. You're saying that Gardevoir is much better than Haxorus and doesn't need to set up to destroy stall, while Haxorus needs to. Then you go and say that Gallade outclasses Medicham due to some advantages it has over Medi, especially Swords Dance.
