The Ur-Dragon {4}{W}{U}{B}{R}{G}

Legendary Creature — Dragon Avatar

Eminence — As long as The Ur-Dragon is in the command zone or on the battlefield, other Dragon spells you cast cost {1} less to cast. Flying Whenever one or more Dragons you control attack, draw that many cards, then you may put a permanent card from your hand onto the battlefield.
