Defog Scizor should look like this; it needs the recovery in Roost:
-U-turn
-Bullet Punch/Knock Off
-Defog
-Roost
Nature: Careful
EVs: 248 HP/84 Atk/172 SDef
Item: Leftovers/Scizorite
Ability: Technician
Water/Dark have good coverage together already, so Crawdaunt can get away with using only its STAB moves:
-Swords Dance
-Crab Hammer
-Knock Off
-Aqua Jet
Nature: Adamant
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb/Mystic Water/Splash Plate
Ability: Adaptability
Swords Dance gives Talonflame a bigger boost in Attack; a Bulk Up set plays a lot differently than a Swords Dance set would:
-Swords Dance
-Flare Blitz
-Brave Bird
-Roost
Nature: Adamant
EVs: 48 HP/252 Atk/208 Spe
Item: Life Orb/Sharp Beak/Sky Plate
Ability: Gale Wings
or
-Bulk Up
-Brave Bird
-Roost
-Taunt/Substitute
Nature: Careful
EVs: 248 HP/176 SDef/84 Spe
Item: Leftovers
Ability: Gale Wings
It should be noted that Rain Dance hampers Talonflame's Flare Blitz. I know that it helps against Scizor's Fire weakness, but an outright Fire resist like Wash Rotom is better:
-Volt Switch
-Hydro Pump
-Will-o-Wisp
-Pain Split/Rest
Nature: Bold
EVs: 248 HP/216 Def/44 Spe
Item: Leftovers/Chesto Berry
or
-Volt Switch
-Hydro Pump
-Will-o-Wisp
-Pain Split/Thunderbolt
Nature: Modest
EVs: 228 HP/60 SAtk/220 Spe
Item: Leftovers
or
-Volt Switch
-Hydro Pump
-Hidden Power (Ice/Fire)/Thunderbolt
-Trick
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Choice Scarf
I don't think Rhyperior is a good choice in OU because of its common weaknesses. Sure, Solid Rock compensates, but Water and Grass commonly target Rhyperior's lower Special Defense stat. Tyranitar is still a better Choice Bander in this regard, even though it summons Sandstorm (though it's temporary):
-Stone Edge
-Crunch
-Pursuit
-Earthquake
Nature: Adamant
EVs: 180 HP/252 Atk/76 Spe
Item: Choice Band
Ability: Sand Stream
Gengar must always use a Timid nature; otherwise it's outsped by stuff like Keldeo and Terrakion:
-Shadow Ball
-Sludge Bomb
-Focus Blast
-Thunderbolt/Destiny Bond
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb
or
-Substitute
-Shadow Ball
-Pain Split/Focus Blast
-Disable/Will-o-Wisp/Focus Blast
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb/Black Sludge
Thanks for the feedback.
Wasn't at all sure what the Scizor set should look like, so that helps.
Would Crawdaunt prefer Waterfall over Crabhammer though?
And something that I forgot was Assault Vest Rhyperior. Some people said they've had success with that, and with Solid Rock, I'd like to think it can tank some hits. Rotom is an ideal option for Amoonguss, but idk, subbing for Rotom and TTar makes this team look
extremely standard. I know that's what wins games though, so I'll try to tinker with it and sub one or both of those guys in.
