Jin-Gitaxias (Showcase)

Ward 2

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).
