We've been theorycrafting in the OMcord about the contrary stone and have been unable to find any broken sets in theory. The stone is just super flawed, primary fighting type doesnt synergize with anything really in the game atm and opens you to revenge killing by all espeeders. Deo-s is probably the only potential user but it is still fodder to espeed, loses stab on psycho, maybe superpower will work sometimes but not enough to make it broken.
After further consideration, I think yall are right, and staraptite might be kinda mid. I tried to find literally any set that felt broken, and none of them do. I think a lot of people will end up getting tricked by contrary CC, which seems wayyyy worse than either superpower or draco meteor(and it's ilk).
In terms of actually viable sets, there's like 4 ideas that felt compelling. I'm not convinced by torterra just yet, but great tusk typing is never bad, and synthesis is a strong point in its favor. Being slower than ho-oh just feels like a non-starter to me. Anyway, without further rambling:
Okidogi (M) @ Staraptite
Ability: Toxic Chain
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Superpower
- Drain Punch
- Gunk Shot/Ice Punch
- Thunder Punch/Rock Tomb/Throat Chop
This could also be something like conkeldurr if you value mach punch over the extra speed from ogi.
Archaludon @ Staraptite
Ability: Stamina
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
IVs: 0 Atk
- Draco Meteor
- Aura Sphere
- Flash Cannon
- Roar/Dragon Tail/Thunderbolt/Earthquake
The strongest of the Draco Meteor sets I theorized. Hydreigon and Noivern can do something similar, but they rely on focus blast for fighting stab. They get u-turn and more speed, which is nice, but the added bulk and reliable aura sphere on arch feels better to me. Modest 2hkos most ho-oh sets with draco, but really can't do shit to dragalgite magearna.
Deoxys-Speed @ Staraptite
Ability: Pressure
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Superpower
- Extreme Speed
- Ice Punch
- Rock Slide/Thunder Punch
This one is the most obvious pick, and it's pretty good. Problem here is opportunity cost. I would basically always prefer zygardite on this guy for the role of "2nd fastest attacker". I think psycho boost might be bait with no stab boost. Maybe special attacking is better though, idk.
Magearna @ Staraptite
Ability: Soul-Heart
EVs: 252 HP / 4 Def / 252 SpA
Quiet Nature
IVs: 0 Atk / 0 Spe
- Aura Sphere
- Fleur Cannon
- Thunderbolt
- Trick Room
Probably the actual best abuser. This thing seems like a menace in the late game. Fleur cannon into +2 Thunderbolt needs very little chip to guarantee a ko on max hp Ho-oh. Will this be better than Eelectrossite for the sweeper role? Probably not. But it does do something meaningfully different than other mag sets, which can't be said for deoxys.
As far as I can tell, the only truly new sets to come from this stone are just ok. Its best abusers generally have something better to do. I can't believe I'm saying this, but Staraptite may not be ban worthy. It might even be kinda bad. Either way, expect this stone to be spammed on low ladder.
