The comprehensive resource for budget commander deckbuilding
Two‐Dollar Commander, also known as “2DH”, is a Commander (or EDH) variant format where each card in your deck costs $2 or less. Newer players, and players on a budget can build competitive decks, without breaking the bank.
The beginning of the Commander season starts with the release of new Commander products. For 2017, it starts August 25th.
Whenever a product featuring a booster box has a pre‐release, all Commander‐legal cards in that set that are $2 or less are immediately added to the pool. Two weeks after the product’s official release, the pool is updated to include any Commander‐legal cards ever that have newly reached $2 or less.
Any card that is in the pool remains legal until the end of the season, even if the price jumps over $2.
Cards as commanders are a bit more lenient. They are legal when priced at $5 or less.
