Skunktank is the best answer against deoxys-s. Wut. Because sucker punch and aftermath? There are better pokemon to fill that role while filling many others such as bisharp mandibuzz etc.
So you're going to set up sun and wait a turn to recharge to try to kill blissey with a special attacker?
So when ninjask uses defog I can OHKO it's weak body. Okay
Lanturn as good as rotom? Lanturn doesn't have levitate that alone makes it vastly inferior to rotom.
1. An Adamant Skuntank can do 82.8-97.3% damage to standart Deo-S with Crunch. Mandibuzz has problems with Taunt and Trick, while Skuntank really doesn't care about Trick. Also, Mandibuzz is Stealth Rock weak, Skuntank not. Skuntank is a utility Pokemon, filling muliple niches in one Pokemon. It can use Sucker punch to hit a target with Priority, Defog, Puirsut trap AND cripple potential physical attakers.
Bisharp can do everything Skuntank can, bit it can't defog. Mandibuzz can defog really good, but its not a decent pursuit trapper. Skuntank is a utility pokemon.
2. This was just to demonstrate Charizards sheer power. Blast burn should really only be used if you are going to die because of solar power in this turn or when you face something that heavily troubles your team. (The Zard called silly didn't have solar power and sun wasn't up...)
3. Ninjask is a lead. When you lead against something like Ferrothorn, you will probably get a free substitute, when you use substitute at the same time he uses Spikes. Defog when you are behind a substitute.
4 Atk Ferrothorn Power Whip vs. 252 HP / 252+ Def Lanturn: 248-294 (54.6 - 64.7%) -- guaranteed 2HKO after Leftovers recovery
4 Atk Ferrothorn Power Whip vs. 252 HP / 252+ Def Rotom-W: 168-200 (55.2 - 65.7%) -- guaranteed 2HKO after Leftovers recovery
They have similar Physical bulk with maximum Investment.
252 SpA Roserade Giga Drain vs. 252 HP / 252+ SpD Rotom-W: 164-194 (53.9 - 63.8%) -- guaranteed 2HKO after Leftovers recovery

Better Special bulk with Max investment.
Lanturns bulk is better. The only difference between Lanturn and Rotom-W is the different immunity. Paired with a Flying type mon like Talonflame or Staraptor, or with Rotom-H, the Ground weakness dosent matter.
