Granite, Scrapwork Steelhulk

Affinity for Artifacts, Trample

As an additional cost to cast Granite, you may sacrifice any number of artifacts you control. Granite enters with a number of +1/+1 counters, equal to double the amount of artifacts sacrificed while casting Granite.

When Granite dies, create a number of Junk tokens (It's an artifact with "{t}, Sacrifice this artifact: Exile the top card of your library. You may play that card this turn. Activate only as a sorcery.") equal to Granite's power
