Ethersworn Sphinx

Affinity for artifacts (This spell costs {1} less to cast for each artifact you control.)

Flying

Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card with lesser mana value. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)

Intent: Most Esper sphinxes have minimal filigree enhancement, but this sphinx has been extensively enhanced.
