Rulings

From the The Hunted release notes

You cannot start a game with Graphene Chelicera equipped as it is a card with the token-type (token-rarity has no bearing on whether a card can be equipped at the start of the game).
Graphene Chelicera triggers when it resolves on the stack and becomes an attacking card against a marked hero. When this trigger resolves, the current Graphene Chelicera attack gets go again. Future or previous Graphene Chelicera attacks would not be impacted.
If an effect says “Equip a Graphene Chelicera”, you will create a Graphene Chelicera token that enters the arena equipped. You must have an empty weapon zone with nothing equipped to it when the effect begins to resolve in order to create and equip the Graphene Chelicera token.
You do not equip a Graphene Chelicera token if you are unable to create that token (the effect fails).
If Uzuri would put Graphene Chelicera to the bottom of the deck, instead it ceases to exist.

Keyword notes

Stealth

Stealth is an ability keyword written on the text box of a card.
There is no meaning to the keyword ability itself. It is used as an “empty” ability that is used by other abilities.

All keywords

Go again - Go again allows multiple actions to be played in a turn when usually playing an action with use up your action point, and therefore end your turn. A card with go again gives the controller of that card or activated ability 1 action point when it resolves.

When an action with go again resolves, its controller gains 1 action point.
Multiple instances of go again on the same card or activated ability do not stack. If a card or activated ability has multiple instances of go again when it resolves its controller gains 1 action point only.
If an action with go again does not resolve, its controller does not gain 1 action point.
You cannot reveal a card with no to Belittle. The card must have a value to its power that is 3 or less. (0 is a value)
