Shiori Novella, The Archiver

Lifelink
Shiori's power is equal to the number of cards in your hand. You have no maximum handsize.

If you would draw a card, you may reveal the top two cards of your library instead and put them into your hand. If you do, You lose life equal to the combined mana costs of both cards.

Archivist - When Shiori enters, search each players library for a card and exile it face down. You may cast those cards as long as you control Shiori.
