No credit for the set? R00d ;( (Unless you somehow thought of it before I posted my Next Best Thing entry)
I want to nominate Thundurus-T from B- to B. As I'm aware Tornadus-I is in general a better mon, I bring a "new" set that is likely similar to his cousin, Tornadus-T
Thundurus-Therian @ Assault Vest
Ability: Volt Absorb
EVs: 244 HP / 252 SpA / 12 Spe
Modest Nature
- Volt Switch/U-turn
- Focus Blast/Superpower
- Thunderbolt/Knock Off
- Hidden Power [Ice]/[Flying]
As Torn-T is a much better mon in general with higher speed to thread HO, Hurricane spam, and Regenerator, it also adds electric weakness, while Thundurus gets a way to recover some HP and inmunnity to T-wave. This combined with 145 Sp Attack and modest nature makes him a good choice to manage stally teams, specially T-wave users like Klefki, Clefable, Ferrothorn, or Thundurus-I (I know this last one is not defensive but whatever). Electric type add no additional weakness, while Flyng and Steel resistances make him able to switch in vs some pokes Tornadus-T can't.
Mandatory calcs:
+2 0 Atk Technician Mega Scizor Bullet Punch vs. 244 HP / 0 Def Thundurus-T: 123-145 (34.1 - 40.2%) -- guaranteed 3HKO
252+ Atk Talonflame Brave Bird vs. 244 HP / 0 Def Thundurus-T: 105-124 (29.1 - 34.4%) -- 5.8% chance to 3HKO
252 SpA Choice Specs Raikou Hidden Power Ice vs. 244 HP / 0 SpD Assault Vest Thundurus-T: 146-172 (40.5 - 47.7%) -- guaranteed 3HKO
I think I might support Thundurus-T to B-, though it's fine in C+ really. This Assault Vest set is really great at checking opposing Electrics with Volt Absorb and tanking hits from special attackers in emergencies. As mentioned, it's not a bad check to Scizor and Talonflame (aside from Offensive Swords Dance in Talonflame's case) either. I do think that Agility is a more notable set for it, however, along with possiblity Double Dance and Scarf.
Its niches from Thundurus-I make B- a good possiblity, but C+ is still a good spot for it to represent that competition that it has with it. It could go either way. The link to the NBT entry has replays btw if anyone wants to see AV Thundy-T in practice.
