User recovers the item it last used up.

Recycle allows the user to re-use a consumable item if it has already been used in battle.
If an item has been recovered through other means (such as Harvest or Pickup) it will count as consumed and can not be recycled.
Recycle can not recycle items that were knocked off or destroyed by Incinerate. A burst Air Balloon can not be recycled.
Recycle fails if the user is already holding an item.
Recycle can be stolen by Snatch.
Recycle can not restore items lost through Bug Bite or Pluck but can recycle the user's berry if it was consumed through Teamtime.

• In Gen 3 a held item becomes permanently lost if the user gets an item knocked off, then uses a consumable item and then recycles that consumable item.
  The originally held item is then gone.
• In Gen 3-4 the way the recycle check works is by field position, so a Pokémon can recycle an item that another Pokémon used earlier in its spot.
  Recycle can not be stolen by Snatch
  Items consumed by Fling, Bug Bite, Natural Gift or Pluck can be recycled.
