Powerstone

Powerstone is a predefined token and artifact type introduced in Dominaria United.

Description

Each Powerstone token has the artifact subtype “Powerstone” and the ability “: Add . This mana can't be spent to cast a nonartifact spell.” All generators of this token create them tapped.

Powerstones were previewed with Karn, Living Legacy and The Mana Rig in Dominaria United, and became a main mechanic in The Brothers' War.

Nontoken cards

Cards with the Powerstone type are:

• The Mightstone and Weakstone

Non-Powerstone cards

Three artifacts, all of which generate mana, have "powerstone" in their name. None have the nonartifact restriction.

• Worn Powerstone
• Powerstone Shard
• Fractured Powerstone

Rules

Rulings

• You can use the added by a Powerstone token on anything that isn't a nonartifact spell. This includes paying costs to activate abilities of both artifact and nonartifact permanents, paying ward costs, and so on.
• Although all the cards in the Dominaria United set that create Powerstone tokens create a tapped Powerstone token, entering the battlefield tapped isn't part of the token’s definition. Notably, if you create a token that is a copy of a Powerstone token, the token copy won’t enter the battlefield tapped.
