Creature — Human Artificer
2 / 5
At the beginning of your end step, create a tapped Powerstone token. (It's an artifact with "

: Add

. This mana can't be spent to cast a nonartifact spell.")

: Draw a card and put a +1/+1 counter on this creature.
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.
