Jo'el, Arcane Infuser

When this creature is in the command zone or
on the battlefield, you cannot cast artifact spells.
Eminence — {x}, put an artifact card with
converted mana cost X or less into play from
your hand. Counter the next spell you cast.
{b}{r}, Sacrifice an artifact: target spell gains
storm. (When you cast that spell, copy it for
each spell cast before it this turn.)
