Creature — Dwarf Shaman

This creature gets +1/+0 for each artifact you control. Magecraft — Whenever you cast or copy an instant or sorcery spell, create a Treasure token. (It's an artifact with "T, Sacrifice this token: Add one mana of any color.")

A captured elemental makes for a potent, albeit unstable, power source.
