Colored gems are white, blue, black, red, or green.
- Colored gems may become Support gems when a support is played.
- Colored gems may become Activated gems when a card with an activated ability is played.
Loyalty gems generally can't be converted into other gem colors or types unless explicitly specified.
When a support card or support Token enters play, a colored gem becomes a Support gem.
- If possible, the support is placed on a gem matching a color of the support.
- If that's not possible, the support may be placed on any colored gem.
Support gems enter play with a numerical shield value. The shield value represents the durability of the support.
The side of the gem on which the shield value is shown corresponds to the player who controls the support.
Support gems can't be converted into other gem colors or types.
Support gems which are reinforced gain a circular icon around the shield value.
Support gems with Mana Field have a large glowing halo during the controlling player's turn.
Creating support gems
Support gems can be created by:
- Playing a support card from hand.
- Playing the same support card again reinforces the existing support gem, unless otherwise specified.
- Using a card or an ability to create a support tokens. Types of support tokens are described below.
Matching support gems
Matching or hitting a support gem by a match-4 reduces its shield by 1. If the shield goes to 0, the support is destroyed. Some supports are indestructible and have infinite shields.
|Type of indestructible support||Effect of matching|
|Created by a player's card or loyalty ability||No effect (unless otherwise specified)|
|Part of an event node's special rules||Changes the support gem's color to a random color|
Types of support gems
Support gems created by an ordinary support card act as described on the card. Ordinary supports reinforce if played when you already control the same support in play, unless otherwise specified on the card. When a support gem which was cast as a support card is destroyed from play, the support card enters the graveyard.
Support tokens are created by effects rather than being cast as a card. When destroyed, support tokens do not enter the graveyard; they just disappear. Support tokens have the same appearance on the gem board as support cards, and unless otherwise specified are affected by the same effects and abilities that affect support gems cast as cards.
|Clue token||Doesn't reinforce||
|Supporting Servo token||Doesn't reinforce||
|Food token||Doesn't reinforce||
|Treasure token||Reinforces only when you have 4+ treasure tokens in play||
|Others||Reinforces unless otherwise specified||Many other support tokens can enter play from card or planeswalker abilities, many with unique effects.|
Vanguards are a special type of support card representing planeswalkers. They have a different appearance on the gem board to card or token supports.
Vanguard cards enter the gem board as Vanguard support gems when played, and are reinforced if already in play when played again. Vanguards have passive and active abilities which their controller can benefit from.
By default, effects which work on general supports don't work on Vanguards; Vanguards are only affected if it's specifically stated on the card or effect. For example:
- A card which says "Destroy a support." doesn't affect Vanguards.
- But a card which says "Destroy a support. This effect can affect Vanguards." does.
Matching or hitting an activated gem with a match 4 destroys the gem and produces an effect which depends on the type of the activated gem.
Activated gems are created from existing colored gems, and keep their color after becoming activated gems.
Activated gems can't be converted into other gem colors or types.
|Activated gem type||Image||Effect|
|While in play||When matched|
|Activate||No effect||Triggers an effect on the card which created the activate gem|
|Adapt||No effect||The creature which created the adapt gem gets +1/+1 and has its Adapt ability triggered|
|Countdown||Counts down by 1 each turn and triggers the match effect on zero||
|Energize||No effect||Can trigger an Overload effect on your cards in play|
|Enhanced||No effect||When matched with a swap, adds 1 to the Enhanced value of your first card in hand which can be Enhanced|
|Graveyard||No effect||Adds 3 mana to the first card in your graveyard with Buried|
|Ignited||Counts as an Improved Gem||Destroy a block of 3x3 gems around the ignited gem|
|Snow||Can trigger Snow effects on cards||Adds 1 mana to the first card in your hand with Snow ; can trigger additional Snow effects on cards|
|Trap||Invisible to the player.
(However, the AI sees your traps!)
|Triggers an effect on the card creating the trap gem|
Void gems are empty bubbles created by cards with the Ingest ability.
Cards with the Process ability require void gems on the board to work.
Matching 3 or more void gems gives:
- +1 mana per gem to a card in hand with the Devoid ability
- No extra mana from any coloured mana bonus
- +1 loyalty
If you have no Devoid cards in hand, matching devoid gems gives no mana.
