Antique Collector
This creature can’t be blocked by creatures with power 2 or less.
When this creature enters, creatures you control perpetually gain “When this creature dies, you may shuffle it into its owner’s library if it’s in your graveyard. If you do, investigate.” (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)
