The rules for the Peasant format are as follows:
1) Your deck may only include common :common: and uncommon :uncommon: cards.
2) You may not include cards from Campaigns
3) Cards that transform themselves or other cards into random cards or other cards into a rarity other than common and uncommon are banned. Ex. Unstable Form
4) Cards that create cards of a rarity other than common :common: and uncommon :uncommon: into play, your deck, or your hand are banned, this includes Invoke.
--4a) There is an exception here for cards that add cards to your Market. Choosing to draw a card that is not a common :common: or uncommon :uncommon: from your Market will result in a game loss.
These rules are to keep the format to it's intended design with cards of power level around the intended rarity. Campaigns are disallowed to lower the barrier to entry to the format. The ideology of the format is to keep it accessible to even the newest of players that just downloaded the game.
