Time to talk about these guys (The relevant ones)
Metagross: While Gross was eh in XY, I think he'll definetely be good this time around. He's a great check to Fairies and Psychics, and with 130 attack has a powerful offensive presence. It's problems are still here though, as his typing is both a gift and a curse, but the curse is most apparent, as types like Fire, Ground, and Dark are still very common. Overall, I think Metagross will be a neat addition to the tier, as it can wall a lot of things while still hitting hard, but it still has some faults.
Potential Sets:
Metagross @ Lum Berry / Life Orb
Ability: Clear Body
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Agility
- Meteor Mash
- Zen Headbutt
- Earthquake / Ice Punch
Agility Gross could be a great sweeper late-gamer, with Gross' good coverage and set-up abilities. With Adamant, +2 speed lets it's speed be 478, basically outspeeding every non-Scarfed mon in the metagame, also allowing it to have maximum attacking power. Definetely will be a great sweeper.
Metagross @ Assault Vest
Ability: Clear Body
EVs: 252 HP / 252 Atk / 4 Def
Adamant Nature
- Meteor Mash
- Zen Headbutt
- Earthquake
- Ice Punch / Grass Knot
This lets it wall the stuff it walls a bit easier, along with living basically any neutral special attack. AV also lets it have maximum coverage, which is great as well. EV spread could definetely be a bit tweaked to be more speedy though. Overall, AV Metagross can be a great offensive special sponge.
(grass knot 2HKOs Mega Swamp even with Adamant, btw)
Gardevoir: Gard seems pretty cool, Scarf mentioned above might be a cool late-game cleaner, I can also see stuff like Life Orb or even Offensive Calm Mind working. It still has pitiful physical defense and average speed, but it's definetely cool to have another Fairy. Also, Trace can lead to some cool stuff, like Flash Fire or Dry Skin.
Potential Sets:
Gardevoir @ Life Orb
Ability: Trace
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Psyshock / Psychic
- Moonblast
- Focus Blast
- Energy Ball / Shadow Ball / Calm Mind
This set hits very hard, thanks to Life Orb and Gardevoir's 125 special attack and excellent coverage. While it suffers a bit from Gardevoir's 80 speed, I think this set can serve as a really nice wallbreaker.
Scarf is said above.
Diancie: Okay, Diancie isn't the greatest mon ever, but I feel like it could a cool addition, especially with stuff like Fire types and Flying types on the rise, so it's Rock/Fairy typing can let it wall a lot of things. It isn't that passive either, with 100 attack and 100 special attack stats along with powerful Base Power STABs let it hit hard. it's typing, like Metagross, is a gift and a curse as well, and it's 50 HP hurts it's amazing defenses. But overall, Diancie could be a nice addition with it's typing and moves.
Potential sets:
Diancie @ Life Orb
Ability: Clear Body
EVs: 252 Atk / 252 SpA / 4 HP
IVs: 0 Speed
Quiet Nature
- Trick Room
- Diamond Storm
- Moonblast
- Earth Power
This is OTR Diancie. It could probably work pretty nicely on Trick Room teams, or even on it's own, with Diancie's nice mixed attacking stats. It's STABs hit really hard with Life Orb, and it's slow enough to outspeed a lot of mons under TR. Earth Power is for Steels, giving Diancie nearly perfect coverage.
SR Diancie can also work but I haven't gotten a good enough EV spread for it yet.
Mini talk-abouts:
Venusaur: Seems like the child of Amoonguss and Roserade, having balanced defensive stats as well as nice special attack. Might receive some competition, though.
Manectric: Other than Overheat and LightningRod, outclassed by Heliolisk, Galvantula, and Zapdos.
Sableye: ewww Prankster
Charizard: Useless pretty much, I can see low ladder ABUUSING this thing though. C'mon low ladder guys, RU and NU want it too!
Overall, the UU meta is gonna change a lot with the addition of these new base forms, and I like it! I can't wait to try out stuff like Diancie and Metagross! Go UU! =)
Also #PrayForRU it has like no counter to normal Sharpedo dudes.
