Limited Time, Limited Quantity Decorations?

How about offering Decoration Items with Limited Time or Limited Quantity for purchase with Gold or GEM.
players can decorate them or put them in storage.
Players can also put them up for auction to be bid by other players for Gold or GEM.
SuperCell can create a whole new marketplace for Clash of Clans

Tbh I would rather be spending my resources on my village than buying a decoration that's going to disappear after a time.Seems a bit pointless really.
Decorations are such an insignificant part of the game I don't see the need to mess
