Weezing @ Black Sludge / Air Balloon
Trait: Wonder Guard
EVs: 252 HP / 252 Def / 4 SDef
Bold Nature
- Will-O-Wisp
- Sludge Bomb
- Taunt / Haze
- Pain Split
Level 51 completely wrecked me with this thing, not hard to see why. Wonder Guard Weezing only has 2 weaknesses which means the only things that can defeat it are powerful Ground / Psychic moves or Mold Breaker. The fantastic thing about Weezing is that it has pretty decent physical bulk, meaning that it doesn't just crumble to Teravolt Terrakion like most other Wonder Guard Pokemon do, especially if it's running Air Balloon to avoid Earthquake. Unlike the other Wonder Guard Pokemon, Weezing can also burn Mold Breaker mons, which is great given that most of them are physically inclined.
In addition, Teravolt/Mold Breaker Pokemon are pretty essential on every team; they are the only things that beat Sturdy Shedinja and Wonder Guard Pokemon without resorting to weird moves. Pokemon that get these include: Mew, Metagross, Terrakion, Tyranitar.
I don't think there's anything that's blatantly overpowered rn (overcentralized, yes lol), with Wonder Guard keeping many powerful Pokemon in check and Teravolt / Mold Breaker keeping those in check.
If we're talking about prankster, you can't not talk about pansage. This thing functions as a pseudo shedinja.
Pansage @ Focus Sash
Ability: Prankster
Level: 2
EVs: 252 HP
- Endeavor
- Leech Seed
- Recycle
- Taunt
Leech seed basically tops of its hp every time because it's lvl 2. Endeavor gets the opponent into the range where he's killed by leech seed. Recycle to stall using focus sash+leech seed. Taunt to prevent status.
There are a number of ways to stop this strategy; for example, making use of entry hazards, Grass-types, Pokemon with status moves (Pansage has to risk being hit by an attack if it tries to Taunt), Magic Guard, priority moves, or simply switching between Pokemon with recovery moves and PP stalling. Honestly I don't think it's as useful as you make it out to be, though it's fun and all.
Also if anything a Timid Nature with 252 Speed EVs should be used to outspeed opposing Pansage, and to keep HP as low as possible to maximize Endeavor damage.
