No mana is in many regards the opposite of zero mana, as it denotes a cost which cannot be paid. Both have however a mana value of 0.
Any non-land cards with a non-existing mana cost cannot be played unless they have an alternative cost that can be paid, including "casting without paying its mana cost".
Mechanics
Most cards with no mana utilize the Suspend mechanic. In addition, there are the following mechanically unique cards:
- Asmoranomardicadaistinaculdacar — gains an alternative cost if you've discarded a card
- Evermind — can only be spliced
These cards are the second-most common recipient of color indicators after double-faced cards, since they have no mana cost to define their colors.
Conspiracy and Dungeon cards also have no mana cost, but they are not permanents or spells and are only ever in the Command zone, making corner cases of being cast less relevant.
Acorn mechanics
Multiple acorn 
cards function without mana cost. The Augment mechanic can be used to play a card on a host creature. In addition, there are the following mechanically unique cards:
- Entirely Normal Armchair — must be hidden on the battlefield
- Standard Procedure — becomes a different card.
Attraction and Contraption cards also do not have mana costs. They are however part of respective side decks that use a different method to be put onto the battlefield.
Rules
From the Comprehensive Rules (November 14, 2025—Avatar: The Last Airbender)
- 118.6. Some objects have no mana cost. This represents an unpayable cost. An ability can also have an unpayable cost if its cost is based on the mana cost of an object with no mana cost. Attempting to cast a spell or activate an ability that has an unpayable cost is a legal action. However, attempting to pay an unpayable cost is an illegal action.
- 118.6a If an unpayable cost is increased by an effect or an additional cost is imposed, the cost is still unpayable. If an alternative cost is applied to an unpayable cost, including an effect that allows a player to cast a spell without paying its mana cost, the alternative cost may be paid.
