Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
In a random battle I just had, Trick worked despite the fact that there was a substitute.
Edit: Dark Pulse also goes through Substitute.
Edit 2: Banette shouldn't be able to use Shadow Force in the Randoms.
Supposedly Mr. Mime gets Charm and Healing Wish without requiring Mime Jr. Can anybody check Charm with Gothita-line(Healing Wish can't be tested now)?
Nosepass is supposedly one of the Pokémon that now gets Wide Guard according to the Japanese Kalos Pokédex guide, but it can't be checked until Poké Transporter is released.
Though it currently can't be tested, Litwick supposedly gets Power Split as an Egg Move(obviously from Yamask) according to Japanese Kalos Pokédex guide.
