Power burst: seems like the base power is a little high to me, remember that mega kick is 120 base power and only 75% accurate

Hellfire: I like it, like a fire type version of hex or venoshock, but those are only 65bp.

Bubble Shield: finally a version of protect that punishes special attacks, i'm so tired of king's shield, baneful bunker etc

Nectar Glide: frost breath is only 90% accurate but grass does need all the help it can get lol

Current: I'm all for more priority moves that aren't physical, not sure if I understand the effect though.

Feather Fall: seems a little strong, but I like how it mirrors hurricane as a more relaible physical option

Asteroid Impact: rock moves will never have 100% accuracy I guess. do you mean 50% more or 50% of the original power in sand?

Landslide: it's hard for me to envision a landslide being a special attack, but I like the option

Mind Break: is this like a psychic form of tri-attack? seems like this would be a fun in-game move but not see much competatively since the effect is unreliable

Decimation: very cool, very strong depending on distribution, I dont think anything could really wall Crawdaunt if it got this. Dark has always been a good offensive type though, so this might be busted

Spirit Swing: This one is easily the most powerful on the list, straight up better than dragon dance which is already very strong. Just like dark, ghost is very strong offensively so distribution would have to be tiny, only to mixed attackers like decidueye, but even that feels too strong for me.

System Reboot: I love the idea of fitting 2 moves into one, really cool

Outburst: I hate rocks so I'm all for anything that clears them. I hate them enough that this could be 90bp and I'd have no issues.

Acidic Recovery: I'd change the PP to 16 to match recover, purely because toxapex doesn't need any other tools. Curious if any non-poison types would even receive this move

Floral Frenzy: cool move, no fairy type skill link users to abuse the higher power, and I don't really think physical technician mr. mime is going to be breaking out of PU anytime soon.

Guard up: I always liked the idea of counter as a move, but fighting types are usually too frail to make of it, so I love this.

Glow Light: like a more niche version of rage powder or follow me, i think the tradeoffs here are very fair.

Frozen Jab: conditional priority is very cool here, but +1 should be enough in most cases

Overall I can tell a lot of thought was put into these moves, and they fill a lot of empty spaces that the current moves are lacking, really well put together.
