I voted for Hyra's again. I stated my reasons in the other thread, but to sum it up in one sentence:
"I see this acting just like Infernape: It's hard to get in, but once it does, it can steamroll through entire teams."
Hyra's set seems to have the most potential for this (it's much easier to take down physical walls with Ice Beam/Blizzard than it is to take down Blissey with Megahorn.) MWL's set can 2HKO Blissey with Megahorn if it runs max attack + Naughty, right? That's not so great. That's only for 104 HP Blissey's, and most run more. Plus, needing to run so much attack AND boosting nature JUST to take down Blissey seems like way too much. It means he won't be able to outspeed things that he's supposed to like Infernape, Gengar, and the 115 and 120 groups. It also means he won't be hitting as hard with his Special Attacks, despite having a higher Sp. Atk. stat. Hyra's can kill Blissey much more easily, and still eat the physical walls alive with his special attacks.
Oh, and stop acting like MWL's can take hits if it needs to. It's about as frail as Infernape, and he's not exactly known for his defensive prowess. Honestly, priority moves are about ALL it's going to be surviving. Sure, that's pretty good compared to Hyra's, but honestly. . . I see his switching out a lot more, which is NOT what you want to be doing with a 50% SR weak.
Now, I know some of you are going, "MWL's set is going to be switching out? Did you even look at Hyra's defensive spread?" Yes, I did. You don't need to switch if the enemy is dead. Guess what? That's a far more likely situation with Hyra's spread.
I just ran the calcs: Heracross (125 base attack, same as Hyra's) does 51.40% - 60.41% to a 104 HP/252DEF Bold Blissey with 252 ATK EVs and a NEUTRAL nature using Megahorn. It's not a guaranteed 2HKO, but it's still a pretty good chance, and guess what? It's a guaranteed 2HKO in Hail. This leaves him free to run a +Speed nature, giving him LOADS more potential. It requires a minimum of 216 EVs to fetch a guaranteed 2HKO in Hail (neutral nature, of course).
Please, if you don't like my argument (or, quite possibly, find something wrong with it), go ahead and argue. I'm always up for losing a debate.
Although, seeing as MWL's is winning by a mile at this point, I seriously doubt any of this means anything =[
The reason we care about defenses is that Hyra's spread is so poor defensively that every popular Steel wall can OHKO it
without residual damage.
Meaning that if this gets a perfect, damage free switchin and doesn't get poisoned/paralyzed/burned, it has a 0% chance of winning any encounter with any steel wall.
Lets say that we max attack on this and give it enough speed to beat Jolly Duggy with a -Sdef nature:
Stats:
HP: 235
Attack: 349
Defense: 186
Special Attack: 253
Special Defense: 153
Speed: 373
Now before we begin, are you noticing a problem in particular. If you aren't, notice your SA is hanging just above 253. You won't be OHKOing Steel walls with this, even the nuetral ones, any time soon.
Here are Calcs for Megahorn + Blizzard with Life Orb on the most common Steel walls:
Skarmory:
M-Horn. Blizz.
36-42 242-285
Min: 278
Max: 327
Skarm HP:
334.
Steelix:
M-Horn. Blizz.
62-73 214-251
Min: 276
Max: 324
Steelix HP:
354
Max HP 300 Def Bronzong (2 M-Horns)
151-178 each.
Min: 302
Max: 356
Bronzong HP:
338
Here's the tricky part though, Bronzong recovers 21 HP with Lefties, meaning it actually survives 2 max damage Megahorns with about 3 HP to spare.
Which means, even assuming both attacks hit at maximum damage, Skarm and Steelix survive. I didn't even take into account Leftovers here, Stealth Rock doesn't matter in either case, and if you managed to set up Spikes on 'Lix, chances are it used Stealth Rock in the process.
Now the killer:
Skarm Brave Bird (176 Atk)
247-290 Damage (105-123%)
Steelix Gyro Ball (236 Attack, 150 BP based on speed)
411-418 Damage (174-205%)
Bronzong's numbers are similar, as are Forrys.
Now, MwL's spread probably isn't going to eat Gyro Ball's either, but based on MwL's numbers:
Skarm Brave Bird (176 Attack):
260-306 Damage (92.53%-108.9%)
What this means is that with some EV investment in defense or HP, Hyra's variant could actually take a Brave Bird and launch a second attack. It couldn't with LO but if it had Specs it wouldn't be a problem.
Defenses DO matter for a mixed sweeper when it means the difference between getting OHKO'd by the walls it is supposedly designed to break.
One last note: Same EV spread on MwL's (beats Dugtrio, Maxes Attack, +Speed -SD) with LO.
Skarmory:
M-Horn. Blizz.
33-39 256-301
Min: 289
Max: 340
Steelix:
M-Horn. Blizz.
56-68 225-265
Mix: 281
Max: 333
Steelix Max HP:
354
The moral of the story kiddies is that Steelix is a fat POS.
