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 <c>Karn, Living Legacy</c> and <c>The Mana Rig</c> in Dominaria United, and became a main mechanic in The Brothers' War.
===Nontoken cards===
Cards with the Powerstone type are:
*<c>The Mightstone and Weakstone</c>
===Non-Powerstone cards===
Three artifacts, all of which generate mana, have "powerstone" in their name. None have the nonartifact restriction.
*<c>Worn Powerstone</c>
*<c>Powerstone Shard</c>
*<c>Fractured Powerstone</c>
==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.
