King of the Laboratory

Eminence - You do not have any deckbuilding restrictions. Cards that refer to the Laboratory
refer to your Library. Cards that refer to
Creations refer to cards you own. You may play
cards from your hand face down as basic Wastes.
At the beginning of each player's end step, that
player exiles a card from their hand and draws a
card from the Laboratory. Players may spend
mana as though it were mana of any type to cast Creations.
