Reviews once again!
As stated in the OP, during the
Veto / Review Phase, we'll give people a chance to fix potentially broken or extremely weak submissions. Any sub that's vetoed and isn't appropriately nerfed/buffed/replaced
will not be eligible for voting. New submissions can be made and all submissions can be edited during the Veto / Review Phase, but note that newly added things can be vetoed without warning if they are too strong or too weak.
Additionally, this is also a sub review, I'll also be giving feedback on all subs, not just vetoed ones. These are just my opinion, so unless it is a veto, it's up to you whether or not you take my advice. You'll know if something would get vetoed if I put the word
Veto in Bold in the review.

I like it, basically an OU-viable Mienshao and we all know how good fast offensive Regenerator is. I will allow the Flying Press buff since it doesn't effect anything else

Might be a little lacking, Icicle Spear is gonna hit like a truck and this would be really good in Trick Room, but outside of that it seems hard to work as a slow Ice-type. Adding Ice Shard and maybe Swords Dance would help, with the former giving it something frail offensive mons, and the latter making Ice Shard stupid strong

Very neat Toxic spreader, I love the mindgame with Swamp Sweep here. Also noting that Venom Drench would be undexited if this wins (if anything, I only putting this here for myself, this move is very forgettable)

Pretty similar to ErrorMan's weather abusing Hawlucha, but I do like the idea of Hawlucha continuing to abuse Terrains. It also kinda competes with Iron Leaves as a Tera mon for Electric Terrain, so you could maybe consider giving this a Grassy or even Psychic Terrain ability (though the former would of course mess with its STAB EQ), but at the same time keeping this on Electric Terrain does create a triple mindgame between if your Pincurchin, Iron Leaves, or Hawlucha is gonna Tera, which is neat

Very simple and a effective, Scrappy Rapid Spin and STAB Body Press are quite good. I don't personally like unblockable Rapid Spins, but a mon like this does need a big selling point like that

This would be so insane if it had recovery not named Life Dew, even with the Rocks-weak typing, but it doesn't so this should be fine, neat mixed wall

This would get
vetoed, it's just too bulk to have Regenerator, the Fairy-typing, and pivoting. The easiest way to nerf this would be to just replace Regenerator with a much weaker ability, but if you really want to keep that, then I'd reallocate all the boosts to its SpD to Atk, SpA, and/or Speed and remove U-turn. Having a specially bulky Tera Fairy mon does also overlap with Tera Blissey, so you could also consider changing the Tera Type but you don't have to

I really like Hawlucha keeping its field effect abusing ways but in a different context, and the stats and typing kinda make it feel like a Fire-type Roaring Moon, I like it

Another cool wallbreaking Avalugg, being a slow Dark-type is pretty abusable by the meta but those Crunches will hit stupidly hard and it being a spinner that threatens Ghosts is nice

You only have 5 stats listed, I assume you didn't change its 150 SpD. Outside of that, this is a neat midspeed offensive mon, can use its great bulk to set up and try to sweep, kinda feels like a specially defensive Kommo-o that trades utility for bulk. I do think Merciless is a pretty weak ability on this but I see the vision. Maybe you could give it Toxic so it can spread some poisons itself
And that's all! Keep the submissions coming before voting tomorrow!
