During play, mana powers up Cards to allow them to be played.
Each matching of 3 of more gems on the gem board provides an amount of mana according to the number of gems matched, and the mana bonuses of the Planeswalker.
The mana required to play a card corresponds to the card's casting cost, which may range from 1 to 30.
Mana of any of the five colors can be used to pay the casting cost of cards of any color. Other specialised types of mana exist.
|Gained by matching white gems. Pays for any card.|
|Gained by matching blue gems. Pays for any card.|
|Gained by matching black gems. Pays for any card.|
|Gained by matching red gems. Pays for any card.|
|Gained by matching green gems. Pays for any card.|
|Gained by matching void gems. Pays only for cards with the Devoid ability.
Void gems are created by cards with the Ingest ability.
|Loyalty||Loyalty is not mana, but behaves similarly. Loyalty pays for Planeswalker abilites rather than cards in hand.
Loyalty is gained by matching loyalty gems. Also, each colored gem match generates 1 loyalty in addition to mana.
Mana may be gained in several ways.
When gained, mana is automatically assigned to the cards in your hand, from the top down, filling the casting cost of each card fully before charging up the next card.
Gem matches are the most common way of gaining mana. Each gem match on the gem board provides an amount of mana which is the sum of the following:
- The number of gems of the same color which were matched
- The Planeswalker's mana bonus of the color of the gems which were matched
Very large amounts of mana may sometimes be gained in a single turn via cascades on the gem board, where one match leads to another.
In events which are Supercharged, each color match provides an additional 3 mana.
Mana can also be gained from certain cards which provide mana when played, or while in play.
Some Planeswalkers have Loyalty abilities which provide mana.
