Zavon, The Really Unfair

Flash, Vigilance, First Strike
Your opponents can't draw cards.
Spells you control, permanents you control and
you have hexproof.
When Zavon enters, take an extra turn after this one. Then end the turn if it's an opponent's turn.
Your opponents can't take extra turns.
Whenever a spell an opponent controls becomes the target of a spell or ability you control, exile that spell and draw a card.
