There's been a lot of talk recently about the best ways to use Shedinja. I've already mentioned this team in this thread, but I would love to get some real feedback on it, and possibly some suggestions on improving it.

The team revolves around keeping Shedinja safe from all threats. I'm sure everyone is familiar with the initial Skill Swap and Entrainment to give Shedinja Sturdy, which lets him survive any standard attack with 1 hp, which means he still has full hp. He essentially cannot be killed by attacking moves (with some exceptions, which I'll go over). I'm going to copy-paste from my original comment (see above link) a bit so I don't have to re-type everything.

Sturdy Shedinja is weak to the following:

*Status (poison and burn)

*Confusion

*Weather (Sandstorm and Hail)

*Leech Seed

*Curse (When used by a ghost type)

*Mold Breaker, Terravolt, and Turboblaze

*Iron Barbs

*Rocky Helmet

*Stealth Rock, Spikes, and Toxic Spikes

*Ability neutralizing moves (Entrainment, Gastro Acid, Skill Swap)

*Trapping moves (Infestation, Magma Storm)

To neutralize the majority of these threats, here's the team I use. (OU Doubles)

Here's how this team makes Shedinja as safe as he can get. First, a reliable start with Audino's Skill Swap and Carbink's Trick Room into an Entrainment (when Carbink switches out). By turn 2, you have a Sturdy Shedinja in a Trick Room. Turn 3, Audino can use Thunder Wave on Shedinja to protect it from Toxic and Will o' Wisp or other sources of burn/poison. If Audino has already been KO'd, switch in Thundurus to get the Prankster Thunder Wave off. Now, here's where things get situational. If they have someone with Confuse Ray or Swagger, switch to Carbink for a Safeguard. If they have a Leech Seeder, switch to Trevenant for a Forest's Curse (which adds Grass Type to Shedinja, making him immune to Leech Seed). If they have Mold Breaker, Terravolt, Turboblaze, or Iron Barbs, switch in Audino, Carbink, or Trevenant and use Entrainment, Skill Swap, or Worry Seed to neutralize the threat. Trevenant has Frisk to check for Rocky Helmets, and can use Trick to get rid of them Mandibuzz has Knock Off and can also remove Rocky Helmets. Taunt on Thundurus and Mandibuzz stops any attempt at Leech Seed, Curse, Confuse Ray, or an enemy Skill Swap/Entrainment/Gastro Acid. If your opponent sets up rocks turn 1, Mandibuzz has Defog to get rid of them before switching into Shedinja. Saftey Goggles prevent weather, and you don't need Focus Sash in the Trick Room due to Audino's slow speed.

This team is very tricky to beat unless you know exactly what's coming. The setup cannot be Taunted (double Mental Herb ftw) and both Audino and Carbink are very physically tanky. Follow Me doesn't stop this team either, since if I see a Togekiss, Clefable, etc. I will lead with Audino and Thundurus and use Protect and Taunt, then Thundurus switches into Carbink and I get the Skill Swap off, then Protect again and Trick Room and the team continues as normal. Two special moves in a row can sometimes take out Carbink before you can Skill Swap, but most people have either a setup of their own or spread out their moves for the most super effective coverage. The only unbeatable counter to this team is a trapping move (Infestation, Magma Storm, Fire Spin, Whirlpool). It can't be Taunted, and while the initial move does no damage, Shedinja will die at the end of the turn.

This team has worked reliably in the past, but I'm sure it can still be improved. Please let me know if I can make this team better, or if it's just horrible and worthless and I should never use it again.

Edit: /u/TBOJ suggested running Secret Power instead of Aerial Ace since it is physical but does not make contact. Nice idea.
