Taking another stab at OU, I'm testing the waters with a mono-poison team! I've had a pretty good winning streak today with this team, so decided to get it an expert's voice on it for future updates and such~
(Changes in bold)
Drapion (M) @ Choice Scarf
Ability: Sniper
EVs: 252 Attack / 162 Defense / 96 Speed
Adamant nature (+Atk, -SAtk)
- Brick Break
- Night Slash
- Thunder Fang
- Ice Fang
Opener-Drapion set I made up. Hits many common leads Super-effective (Weavile, Gengar, Gyarados, Salamence, and Tyranitar namely) and to wrap it all up, outspeeds them all with only 96 Spd EVs and a Choice Scarf. Sadly, to outspeed Weavile I had to take some Defense EVs which put me back into OHKO range from CB Tyranitar, and CB Salamence (I've never seen anyone lead with DDMence, and Mixmence usually lacks Earthquake so Dragon Claw is a 2HKO). I'm thinking of relocating the EVs back into Defense, since even if Weavile hits me first (50~58% w/ Ice Punch), Brick Break will OHKO anyhow... Fire Fang was replace with Ice Fang 'cause its more logical. If I'm lucky and Sniper activates, anything I listed above is dead...
Gengar (M) @ Leftovers
Ability: Levitate
EVs: 6 HP / 252 Spd / 252 SAtk
Timid nature (+Spd, -Def)
- Substitute
- Hypnosis
- Focus Blast
- Shadow Ball
Trying out the new set posted by Iggy (standard EV spread), dunno how this will fair, so it is still in testing.
Weezing (M) @ Leftovers
Ability: Levitate
EVs: 252 HP / 252 Def/ 6 Spd
Bold nature (+Def, -Atk)
- Sludge Bomb
- Fire Blast
- Will-o-wisp
- Pain Split
Because physical hits are really gay. Weezing can still take hits like a champion, man! Nothing much to say about him, but I sometimes have trouble with Steels if (usually ones named Forretress) my other Steel-hitters are dead end'd, so Fire Blast has replaced Thunderbolt. Will-o-wisp is there because my team is not the most bulky around, and if I can weaken that next Earthquake why not?
Tentacruel (M) @ Leftovers
Ability: Liquid Ooze
EVs: 204 HP / 36 Spd / 96 SAtk / 172 SDef
Calm nature (+SDef, -Atk)
- Rest
- Sleep Talk
- Surf / Sludge Bomb
- Ice Beam / Sludge Bomb
Mhm, Tentacruel sure is an awesome special-sponge (or should I say jellyfish! Harhar, get it?!... "Sponge" like a sea sponge... Oh God...). I hate Salamence and I guess my team has some trouble against him, thankfully most run pure-special sets, but Water / Poison is supposedly not resist by many! I go also drop Water-STAB and go Ice / Poison, I dunno need some input... ResTalk to absorb status for my team, and it keeps Tentacruel alive longer.
Muk (M) @ Black Sludge
Ability: Sticky Hold
EVs: 252 HP / 80 Def / 178 SDef
Careful nature (+SDef, -SAtk)
- Curse
- Fire Punch
- Gunk Shot / Poison Jab
- Shadow Sneak
Bulky and can dish-out hits! Hater of Psychic moves, I really wish it got Sucker Punch, but I guess Shadow Sneak can do. Cursing is good to boost his average Defense, and his Sp. Defense is covered with the Nature and EVs. Fire Punch deals with Steels which my team generally hates (go figure). Gunk Shot has been good to me, and I like immediate power with Muk's STAB. He doesn't get many turns to Curse before being forced to switch-out do to a Ground / Psychic move. But then again, 75% accuracy is still iffy. Shadow Sneak deals with Ghosts and Psychics, though usually only KOs after a few Curses. I might be replacing him, but I likes him. >:
Toxicroak (M) @ Wide Lens
Ability: Dry Skin
EVs: 26 HP / 252 Atk / 232 Spd
Jolly nature (+Spd, -SAtk)
- Swords Dance
- Cross Chop
- Sucker Punch
- Stone Edge
Standard Toxicroak, but I'm running Wide Lens just 'cause having 2 moves with low accuracy and PP is poop. I always thought he was fragile, but I always seem to get in 1 or 2 Swords Dance. Nothing else much to say about this battle toad!
lool, I just read a few different RMTs, and it seems I'm writing a little too much. <_< My bad? Read it anyway!
