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.
Can you clone a few of my Shiny 6IV Timid Darkrai? I can give you a 5IV Adamant Adaptability Corphish with Knock Off, Dragon Dance, Aqua Jet, Double Edge as payment
Can you clone me a 6IV Shiny Timid Darkrai? Holding leftovers, also what do you let us hold for collateral, something of similar value :X? And can you clone more than 1?
What X Stones would you take for the Darkrai? I can offer 5IV Bold Prankster Cottonee with Encore/GrassWhistle/Switcheroo AND Calm Piplup with Hydro Pump/Agility. With the X Stone you'd want.
