Looking at the new mythical. While it probably won't be available in VGC for a while or maybe even ever I had a few possible build ideas:
Bulky Nasty Plot
Pecharunt @ Black Sludge
Ability: Poison Puppeteer
Tera Type: Ghost
EVs: 252 HP / 140 SpA / 116 Spe
Timid Nature
- Malignant Chain
- Nasty Plot
- Shadow Ball / Hex
- Recover
Comments:
Pecharunt has great physical bulk combined with it's ability and signature move and access to recover makes it a decent wall. Timid nature with a moderate investment in speed will allow it to outspeed others in its speed tier such as Gyarados, Heatran, Metagross, Breloom and Abomasnow. Malignant chain with a 50% chance to poison and poison puppeteer also adding confusion in addition to being base 100 with 100 accuracy is just broken. Shadowball will be your main STAB move though Hex will occasionally be the better option with how often you'll be poisoning pokemon. Tera Ghost gives a boost to shadow ball and keep your immunities while removing your ground weakness.
Sub Poison
Pecharunt @ Leftovers
Ability: Poison Puppeteer
Tera Type: Ghost / Water / Steel
EVs: 252 HP / 72 SpD / 184 Spe
Bold Nature
- Substitute
- Poison Gas
- Protect
- Hex
Comments: A take on the classic Sub Toxic Set but using poison gas to affect both opponents with Poison and confusion due to the Poison Puppeteer ability. With such a high Def stat and more even stat distribution this has better bulk than the original Gliscor Sub-Tox build. The added speed investment compared will have it outspeed a number of pokemon in it's speed tier but it won't be outspeeding everything. Ghost Tera keeps your immunities and drops your ground weakness or you can go for another defensive typing like Water or Steel though you probably will want to tesastrilize your offensive pokemon.
