Ornn, The Living Forge

Artifact spells cost {2} less to cast.
Ornn gains a +2/+4 as long as you control at
least 3 artifacts.
{x}{x}{r}{t}: Put a brittle token on X creatures
without a brittle token. If Ornn attacks or blocks
a creature with a brittle token, destroy the token
and deal 3 damage to the creature. That creature
does not untap on its controller's next untap step.
