Hello everyone! I recently upgraded to 5th gen, and I'm taking my first shot at an Uber team, and s far this one has brought me awesome fortune against all kinds of teams. Of course, no team is without faults, and I am here to see what everyone says about my team and what I can do to improve it.
Here's a preview:
*Changes in bold*
And now for the details: :
Spaceman(Deoxys-A)@Focus Sash
EVs: 252 ATK / 252 SPA / 4 SP
Ability: Pressure
Nature: Naive
-Ice Beam
-ExtremeSpeed
-Superpower
-Stealth Rock
This spread may seem strange, but the maximum attack EV's give a good chance to OHKO Ferrothorn with Superpower after SR damage, who likes to switch in on me thinking it can force me out. Deoxys-S leads just go about there routines setting up entry hazards, allowing me to set up my own and proceed to take them out with SB. The focus sash is a little trick I like to use to surprise people who expect the Life Orb variant. I've considered running ExtremeSpeed, but opposing leads rarely have priority moves, so I feel it would be a waste. With this set, I can surely 2HKO all common switch ins, save Choice Scarf Terrakion who is OHKO'd. *Trying out ExtremeSpeed to better deal with Deoxy-S leads, as even getting SR and one layer of spikes can potentially mean the pits for my team. Ice Beam is for Groudon leads thinking they have it easy against me. I hardly ever use his STAB attacks so I'm trying running without one.
Mewtwo@Life Orb
EVs: 252 SPA / 252 SP / 4 HP
Ability: Pressure
Nature: Timid
-Psystrike
-Shadow Ball
-Aura Sphere
-Ice Beam
Mewtwo is my go-to Pokemon for immediate destruction. With these moves, he can 2HKO anything after SR damage save dedicated special walls. The only real threat to this monster of a Pokemon is Arceus and Giratina, the latter of which will attempt a OHKO with Shadow Sneak, which is when my Arceus comes out to play. Mewtwo also causes enough switches to keep boosting attackers off the field, usually ending up with Mewtwo sweeping their team.
MetalAmbipom(Genesect)@Choice Scarf
Ability: Download
EVs: 252 ATK / 156 SPA / 100 SP
Nature: Hasty
-U-turn
-Iron Head
-Ice Beam
-Explosion
Genesect, or Metal Ambipom as I like to call him, holds my core together like glue. He can switch in on many of the Dark, Ghost and Dragon type attacks aimed at my sweepers and threaten to rip a massive chunk out of them with one of its coverage moves. I put some extra EV's into Special Attack to turn many 3HKOs into 2HKOs and to give him a small chance to even 2hit Support Giratina with Ice Beam after SR and a Download boost. *I replaced Flamethrower with Iron Head, as you guys said, it truly is useless in the rain, and Ferrothorn always switches out of Genesect fearing it. I'm going to try Explosion out as kind of a final hurrah for Genesect when hes close to fainting.
Blazer(Blaziken)@Life Orb
Ability: Speed Boost
EVs: 252 ATK / 252 SP / 4 HP
Nature: Jolly
-Flare Blitz
-Hi Jump Kick
-Swords Dance
-Protect
I added Blaziken to my team kind of as an afterthought, and so far he's proven more than worthy. He can use his cookie cutter set to crush a large portion of the metagame even without Swords Dance, and I usually like to use him to clean up the opposing team near the end. I can also switch him in on Ferrothorn and nab a free Swords Dance while it switches out. He is helpless against Giratina and the Lati Twins, but the later can be 2HKOed by Hi Jump Kick after a boost if they choose to Calm Mind predicting my switch.
Lugia@Leftovers
EVs: 252 HP / 176 DF / 80 SP.D
Ability: Multiscale
Nature: Bold
-Whirlwind
-Roost
-Reflect
-Toxic
No team is complete without some kind of fall back wall, and Lugia is always there to lend a hand. Reflect greatly aids my sweepers, and Lugia's godly defenses stop boosting sweepers from breaking through my team. Dragon Tail is my favored move, wearing down the enemies health even further on switches and making it easier for my sweepers to OHKO. *Whirlwind is definitely the better option, and Toxic really helps against Giratina and Arceus. I am Taunt bait though, so that is a concern
Yahweh(Arceus)@Silk Scarf
EVs: 24 HP / 252 ATK / 232 SP
Ability: Multitype
Nature: Adamant
-ExtremeSpeed
-Swords Dance
-Earthquake
-Shadow Force
Arceus. ExtremeKiller set. There's really not a whole lot to be said about this set. He shines best as a revenge killer, being able to survive almost any unboosted attack even without Reflect and get a Swords Dance off, proceeding to massacre the entire enemy team with ExtremeSpeed. I choose Shadow Force over Shadow Claw as I can OHKO Giratina-O after a Swords Dance, and the only safe switch in in the uber tier is another EK Arceus, who is quickly 2HKOed with ExtremeSpeed thanks to my speed investments.
I already know I have lots of problems with Jirachi, Ho-Oh without Stealth Rock and opposing Mewtwo. Any advice is greatly appreciated :)
