Heyaheya everyone. I tried building a team around the Therian Dual-Pivot Core of Landorus-Therian and Thundurus-Therian recently but it ended up rather unbalanced with three Steel types on the team (Heatran, Bisharp, and Lucario).
Landorus-Therian @ Choice Scarf
Ability: Intimidate
EVs: 252 Atk / 36 Def / 220 Spe
Jolly Nature
- Earthquake
- U-Turn
- Stone Edge
- Knock Off
Thundurus-Therian @ Choice Scarf
Ability: Volt Absorb
EVs: 252 SpA / 8 SpD / 248 Spe
Modest Nature
- Thunderbolt
- Volt Switch
- Hidden Power Ice
- Focus Blast
I wanted a powerful Volt Switch user to pair with Landorus-Therian, but also wanted to leave my mega slot open for something other than Mega Manectric, so I paired it with Thundurus-Therian.
Together, they work quite well, and both have good individual coverage (Ground/Rock for Landorus, Electric/Ice for Thundurus), but have a major weakness to Ice and don't appreciate Stealth Rock, though thankfully they both immune Spikes and Toxic Spikes.
Focus Blast on Thundurus allows it to take down Excadrill, Mamoswine, and Ferrothorn, which otherwise present a huge threat to Thundurus.
