I just realized I hadn't posted this great set.
Gen 9 OU Dragon Slayer
Clefable @ Life Orb
Ability: Magic Guard
Tera Type: Steel
EVs: 252 HP / 4 Def / 252 SpA
Modest Nature
IVs: 0 Atk
- Moonblast
- Ice Beam
- Thunder Wave
- Moonlight
For Fire/Water/Grass cores looking to find a way to take out Dragon types, look no further. EVs are for bulk and max Spa. Tera Steel because it is immune to Poison and resists Steel. Magic Guard + Life Orb is for high damage output without needing Specs. Moonblast is powerful STAB, and takes down most Dragons. Ice Beam because many Dragon Types are 4x weak to Ice. T-Wave cripples Dragons you struggle to kill, and moonlight is for healing, because Clefable can't learn Soft-Boiled in Gen 9.
