Keep/Change/Delete

[Elegant_Lilligant]

Personally me change by making it 80 base power and have it be 15% for burn/freeze/paralysis.

Marvel Scale

 

[Harryghost]

It is fine; it's not really broken, otherwise we would have seen overcentralizing usage of this Ability over the years. Keep.

Big Pecks

 

[Okido]

Tentative keep. It's fine, there's nothing wrong with it; it's just really situational.

Magnitude

 

[Harryghost]

It's fine. One of my favorite moves actually, because I really like moves that have an RNG aspect. Definitely keep.

Stakeout

 

[Lone_Garurumon]

Keep. It's actually a pretty good tool for rewarding good reads on switches by encouraging you to choose a move you expect the switch to be weak to to get a bonus on them. And even if you don't make the right read, doubling power is still a lot. I suspect the only reason it hasn't really made much of a splash is because the only two lines that get it aren't very, y'know, good.

Heavy Metal

 

[Harryghost]

Pretty situational, but Heavy Slam Copperajah, for one, absolutely slaps with it. For that alone, I'll say keep.

Honey Gather

 

[Okido]

Keep, I guess? Unlike some other out-of-battle abilities, I can't see a situation where you'd really need to use it (just buy Honey in bulk or use Sweet Scent?) but it's not hurting anything by existing. It's a cute HA for Teddiursa to have, at least, so why not keep it.

Shell Smash

 

[Camille]

Keep, it is a great boosting move.
Geomancy

 

[Harryghost]

Here's a thing; Geomancy is just equivalent to two Quiver Dances. IMO it should have been a no-charging turn move giving +1 Special Attack, +2 Special Defense and +1 Speed. That way, it is not just a copy of another move with a fancy name. Regardless, Geomancy and Power Herb is still a top-tier combination, so keep.

Vise Grip

 

[Chidamari Sketch]

No one will miss it if it gets deleted.

On the subject of a move that actually did get omitted; Pursuit

 

[Camille]

Bring it back, there was no need to remove it.
Pressure

 

[Harryghost]

A decent Ability. Keep.

Razor Wind

 

[Camille]

It wasn't great, so I can see why it was removed.
Force Palm

 

[Harryghost]

It is a decent move, and that 30% chance to paralyze is great. Definitely keep.

Trump Card

 

[Elegant_Lilligant]

Kinda gimmicky, i understand why they got rid of it in gen 8.

Mirror Herb

 

[Okido]

Keep. Hard to have a solid opinion on it right now since the games aren't released yet, but it sounds like it'll be really fun in a competitive setting.

Conversion 2

 

[Camille]

Delete, it is too gimmicky to be helpful.
Silver Wind

 

[Elegant_Lilligant]

Just a bug variation of Ancient Power, Delete

Destiny Knot

 

[Lone_Garurumon]

Keep it. Its battle effect is worthless and never comes up, but also doesn't hurt anything by existing. The breeding effect is absolutely critical and needs to be in the game.

Hurricane

 

[Chidamari Sketch]

I think I'd just leave it as is. I don't think there's anything particularly glaring about it.
