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 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 shield value. The shield value represents the durability of the support.
Support gems can't be converted into other gem colors or types.
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 card||Reinforces unless otherwise specified||While in play as a support gem, a support card acts as described on the card. When destroyed from play, the support card moves to your graveyard.|
|Vanguard||Reinforces||Vanguards are a special type of support card representing planeswalkers. They are immune to general support destruction spells and abilities.|
|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.|
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 can't be converted into other gem colors or types.
|Activated gem type||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|
|Clue||Counts down by 1 each turn and triggers the match effect on zero||The clue's owner draws a card|
|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|
|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.
