My team for 1v1 is Butterfree, Charizard and Porygon-Z, but Butterfree and Porygon-Z is the best for me, here are four mons from different teams that I found really useful.
Porygon-Z @ Choice Scarf/Toxic Orb
Ability: Analytic
EVs: 4 Atk / 252 SpA / 252 Spe
Hasty Nature
- Trick
- Hyper Beam
- Skull Bash
- Tri Attack
The use of Choice Scarf here is for the first priority. A lot of players use this mon in 1v1 and increase the speed, so it moves first. The contradiction is you can’t choose another move. I highly suggest use Hyper Beam (if the item is Choice Scarf), and Trick (if you use Toxic Orb). Hyper Beam usually is a One-Hit KO.
Butterfree @ Leftovers
Ability: Compound Eyes
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Sleep Powder
- Quiver Dance
- Bug Buzz
- Substitute
First make the opposite mon sleep first, then Substitute. Mons usually sleep for 2 rounds, so use Quiver Dance next. Afterwards, if the opposing mon wakes up, the Substitute will take damage for you or fade if it is a super effective move. Continue the cycle then use Bug Buzz. The good thing is the Bug Buzz still does damage to the opposing mon when it is in Substitute.
Shedinja @ Rocky Helmet
Ability: Wonder Guard
EVs: 252 Atk / 4 SpA / 252 Spe
Naive Nature
- Toxic
- Bug Buzz
- Facade
- Shadow Ball
As Shedinja has Wonder Guard, it is almost flawless (?). Toxic the opposing mon so it will die slowly and painfully (okay I’ll be professional again), then Facade the mon, as the power doubles when the opposing mon is Poisoned. If the opposing mon is a Ghost type, then Shadow Ball it. BOOM.
Lopunny-Mega @ Lopunnite
Ability: Scrappy
EVs: 252 Atk / 4 SpA / 252 Spe
Hasty Nature
- Fake Out
- Return
- Focus Blast
- Low Sweep
First use Fake Out (you’ll know why), then Return. This is all I can give you.
I sincerely hope that this will help you.
(I am currently testing Shuckle.)
