Jin-Gitaxias (Serial Numbered)

Ward 2 Whenever you cast a noncreature spell with mana value 3 or greater, draw a card. 3U: Exile Jin-Gitaxias, then return it to the battlefield transformed under its owner's control. Activate only as a sorcery and only if you have seven or more cards in hand.

(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).
