Tamiyo Meets the Story Circle

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)

I — Until your next turn, whenever a creature attacks you or a planeswalker you control, it gets -2/-0 until end of turn.

II — Discard any number of cards, then investigate twice for each card discarded this way.

III — Shuffle up to three target cards from your graveyard into your library.
