Wheel of Mirages

Each player's hand has Phasing, and phases out.
Then, each player exiles the top 7 cards of their library face-down. Whenever a player's hand is
phased out, when they would draw cards, they
exile that many cards from the top of their
library face-down instead, and they may look at
cards exiled by this card and play lands and cast
spells from among them.
When Wheel of Mirages leaves the battlefield,
each player's hand loses Phasing and phases back
in.
