Artifact Creature — Construct

When this creature enters, choose up to one — • Target creature becomes prepared. (Only creatures with prepare spells can become prepared.) • Target creature becomes unprepared.

Niche utility creature for prepare-focused strategies, but the conditional effect and high mana cost severely limit its appeal outside dedicated constructed decks built around the prepare mechanic. Only worth considering if your deck is already heavily invested in prepare synergies.
