So when i read the secret stories of the promo cards, it said that Donald was originally meant to make a Promo for Power Grid.
Edit: theory pointed out there already was a thread about making a Power Grid Promo. Check it out
My addition (which actually doesn't fit the theme as much as many of them older cards):
Windmill2$, Action
+ 1 Card
+ 1 Action
Choose a card from your hand. Trash it, discard it or put it on top of your deck.
When you buy this, put it aside. Gain it after you shuffle the next time.
About the game Power Grid itself:Power Grid is a game where you supply cities with energy and for this have to get power stations that use with coal, uranium, trash or oil. Sometimes you'll also be able to get a windmill that produces green energy without resources, but as you have to bid higher than opponents to get a station, you'll sometimes end up paying too much. Also the turn order in power grid changes every round, giving the leading player the strategically worst position.
It's awesome, try it.
It's a great excuse to wear your halloween lab coat, too.
