HOLY MACARONI THAT'S IT
If the mixed sweeper ends up being the chosen role for the Ice/Bug guy, why don't we make it an (other) Scyther's alternate evo? Well, let's look at the stats:
Scyther: HP: 70 / Attack: 110 / Defense: 80 / Sp. Attack: 55 / Sp. Defense: 80 / Speed: 105 /Total: 500
The fast and furious guy. The defenses are good, but not special, and the Sp. Attack is a shame. Purely physical.
Scizor: HP: 70 / Attack: 130 / Defense: 100 / Sp. Attack: 55 / Sp. Defense: 80 / Speed: 65 /Total: 500
The slow and resilient guy. The Sp. Attack and Speed are pitiful, but it has a really high Attack (lol where's Stone Edge again), and incredible defense abilities, mostly because of his good defensive typing.
And now, Icyzor (lol). Upon evolution, Scyther lost Speed and gained Attack and Defense, turning itself into a bulky Baton Passer and dangerous Quick Attacker (seriously). How should we do with Icyzor? Considering it is meant to be a mixed sweeper, the defenses aren't priority. However, they need to be decent, we don't want a pokémon who dies to Choice'd Splashes.
Firstly, the attack stats. Which will be higher, the physical or the special? We can't simply say "the physical, because both Scyther and Scizor are physical-based" because Gardevoir and her pre-evos were pretty special-based, and they gave us Gallade (obligatory "Gardevoir ir prettier" post).
But I say we should really swap their stats. 70/110/80/55/80/105 becomes 70/55/80/110/80/105. But now, we have that nasty Attack. Icyzor, obviously, would be able to use Swords Dance, but... slight higher Attack than Azumarill's and no Choice Band, with almost no resistances (although Icyzor has some pretty nice ones)? I don't think so. Either raise the Attack, give it Huge Power (lol no), or raise the defenses (lol no²).
So, I say (again): drop the damn defenses. While Scizor dropped its Speed for the Defense (he's the bulky brother), Icyzor needs to drop its defense stat for the Attack (hi mixed brother). I'd say at first "kill the Defense", but we want something that actually doesn't instantly die to Chomp's Quake. So, we can go with the Sp. Defense. HOWEVER, it's HP is the lowest defensive stat it has, so it's better for Icyzor's defensive abilities to ditch the HP. Check for yourself, Defenses are more important than HP (Wynaut and Cubone, for example; one has 95 HP/48 Defense, and the other, 50 HP/95 Defense; guess who is bulkier) in Icyzor's case.
But how much? I'd go with 25, just to get a nice 80 Attack, and a measly 45 HP. Yeah, pretty arbitrary, but it's either the HP (that is lower anyway), or the Defenes (that are still somewhat useful).
So, in the end, we get this:
Icyzor: HP: 45 / Attack: 80 / Defense: 80 / Sp. Attack: 110 / Sp. Defense: 80 / Speed: 105 /Total: 500
Sadly, that's the best I can get with Scyther's stats and without going the obvious "lol 70/70/70 defenses".
But anyway, if this guy were a Special Sweeper, things would be a lot easier (swap the offensive stats), but then, good luck trying to completely IGNORE that its pre-evo had 110 Attack...
Or we could just do it a 70/110/60/95/60/105 Icyzor and say "fuck you, he's in" to the 70/70/70 clan.
