Trading pokemon/items from Powersave is allowed, but you must mention "I used Powersave" in your post/comment if you use it to:

• get items/increase item amounts
• get BP/pokemiles/money to then redeem items
• shinify pokemon
• clone pokemon/items
• anything else that I missed aside from reading TSVs and ESVs

Not disclosing this will be considered scamming as it is hacking, and may result in a ban.

Some people may not want items gained through Powersave, even though there's no way to tell if items are hacked/cloned. Shinifying pokemon changes the trainer ID, rendering them un-nicknameable.

As always, full disclosure is best. Always state if something is hacked and/or cloned, status unknown since it was received from the GTS or elsewhere, legit, or whatever applies to your situation.
