The Ur-Sphinx

#12

Legendary Creature — Sphinx Avatar

Eminence — As long as The Ur-Sphinx is in the command zone or on the battlefield, other Sphinx spells you cast cost less to cast. Flying Whenever one or more Sphinxes you control attack, each player mills that many cards. For each player, you may cast a card that player milled this way without paying its mana cost.

You can, however, pay additional costs. If a spell has any mandatory additional costs, you must pay those costs to cast that spell. If a spell has in its mana cost, you must choose 0 as the value of X.
