The Great Synthesis

(As this Saga enters and after your draw step,
add a lore counter.)
I. Draw cards equal to the number of cards in your hand. You have no maximum hand size for as long
as you control The Great Synthesis.
II. Return all non-Phyrexian creatures to their owners' hands.
III. You may cast any number of spells from your hand without paying their mana costs. Exile The Great Synthesis, then return it to the battlefield (front face up).
