The Three-Persona Problem

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

—I. Exile target legendary creature you control.

—II. Search your library for an Artifact card, reveal it,
put it into your hand, and shuffle your library.

—III. Sacrifice target creature you control. Return the creature exiled with this card to the battlefield under your control with X +1/+1 counters on it, where X is the sacrificed creature's toughness.
