mfw sylveon is over 4% usage now
Also was hoping to get gyarados in UU, but now at least it has the very likely potential to drop with this.
I already think metagross will be pretty good, especially with all the florges spam and it's got a pretty wide movepool with some neat stuff like grass knot.
As for sableye, I now see it fiercely competing for a stallbreaker role with jellicent, as prankster pretty much guaranteed starts a taunt + recover chain and is also really annoying to offense at the same time with priority WoW. The only thing jelly has over it is beating florges and not risking a burn vs suicune.
As for the other four, gardevoir and venusaur could be good but I think they'll have to develop in the metagame first. Diancie, while a little more niche offensively compared to garde due to low HP and speed, i think could still be alright as a TR mon, and provide pretty decent mixed attacking with LO. It sounds good on paper but may not be all to good with 50 base HP. It would be useable to an extent. Manectric, while lightningrod is cool, will have to compete with faster and/or stronger stuff like heliolisk and zapdos. Think it should drop to RU soon tbh.
