(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I — Each opponent sacrifices a nontoken creature of their choice.
II — Investigate. (Create a Clue token. It's an artifact with "{2}, Sacrifice this token: Draw a card.")
III — You may sacrifice an artifact or creature. If you do, create two 2/2 black Romulan creature tokens.
