The star of Dominion: Alchemy will have to generally be the Possession card. Costing a hefty six coins and 1 potion, this card mainly helps you to take charge of another player! You get to implement their hand and play their steps, and any card which you achieve from this possession goes to you instead of them. There's also the Philosopher's Stone card which is really worth 1 coin for each and every five cards within your deck.
