Gomery, Master Smithy

When Gomery enters, create a Treasure token. (It's
an artifact with "{t}, Sacrifice this artifact: Add one
mana of any color.")

Whenever another creature you control enters, you
gain 1 life.

"Adamantine, eh? Never seen any. But I'm sure I could invent and then quickly master the process of working it into all sorts of treasures... Say, have you seen my brother lately?"
