- Leech Seed
- Mean Look
Not many people come prepared for Mean Look, so it's really easy to trap the opponent into a slow, painful death.
If you suspect a move it's weak to incoming, terastalize and poison's got you covered, plus you can't be poisoned anymore. I've nearly swept entire teams with this monster.
Something else you can do is use Perish Song before you send Wo-Chein in and trap the opponent that way.
That almost guarantees a KO if you trap the foe because Wo-Chein takes hits like a champ, and it has Protect to give you a free turn.
If they switch out before you trap them? No problem, trap the next one that comes in and make them uncomfortable.
Things to be weary of, though:
- Some set-up or tank Pokémon can prevent the strategy from working, especially ones that have reliable recovery. (This is where Perish Song can be handy. Nudge, nudge.)
- Taunt locks you into Ruination.
- U-turn, Volt Switch, Flip Turn, etc. allow for switching out despite Mean Look.
- Grass types are immune to leech seed.
Enjoy making your opponent hate you!
