 Design Contests
 Dominion Fan Card Contest
In October 2011 user Davio organized a fan card creation contest. As motivation to receive quality entries, Davio offered a modest prize of an Amazon gift card. Davio received 20 entries and allowed the community to vote on the winner. The chosen winner was Archivist, a card designed by rinkworks. The card was an example of a single card engine, with the following card text:
- Name: Archivist
- Type: Action
- Card Text: +1 Action. Choose one: Draw until you have 6 cards in hand; or + and discard 1 or more cards from your hand.
To the surprise of the community, Davio had secretly contacted dougz and the card was playable for a limited time on Isotropic. This is the only instance of an unofficial Dominion card being playable on the public version of Isotropic.
 Mini-Set Design Contest
As a followup to Davio's contest, rinkworks later launched a far more ambitious design contest. The second contest attempted to create a complete mini-set of cards, with every card in the set being designed, voted on, and fine tuned by members of the community. There was a full subforum dedicated to the contest on the forums.
