Scent Seeker

Haste
Whenever Scent Seeker deals combat damage to
a player, flip a coin. If it comes up heads draw a
card. If it comes up tails, investigate. (Create a colorless Clue artifact token with "{2}, Sacrifice this artifact: Draw a card.")
Possessing a greater sense of smell than any trained
hound, a loosed Scent Seeker will always turn up something of value.
