Marshal Cassidy Miller

First Strike
At the beginning of your upkeep, if an opponent controls any creatures, investigate.
Whenever Cassidy attacks, you may sacrifice all
Clue tokens you control. If you do, Cassidy gets
+X/+X and Trample until end of turn, where X
is the number of Clue tokens you sacrificed.

stupid or are you going to draw?"
