If Drifblim (or any Pokemon who somehow gets ahold of Unburden) uses the item/Natural Gift/Fling and gets the Unburden Speed boost, is the boost lost if Drifblim gains a new item through an opponent's Trick?
If the Speed is kept, what happens if the Pokemon uses the new item/Natural Gift/Fling again? Nothing, an "overwrite" of the previous Unburden for simply double Speed, or quadruple Speed?
