Create three tapped Powerstone tokens. You gain 3 life. (The tokens are artifacts with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.")
Watch Out
Mana abilities don't use the stackRules Note
If this card's activated ability produces mana and doesn't target, it's a mana ability. Mana abilities resolve immediately without using the stack — opponents can't respond to them. However, abilities that target (even if they produce mana) aren't mana abilities.
