Sleeping Guardian

Defender
At the beginning of each combat step you may
flip a coin to attempt to wake up Sleeping
Guardian. If heads, sleeping Guardian is awake, if it is tails he remains asleep. At the end of combat
Sleeping Guardian goes back to sleep.
Awake: Sleeping Guardian has Deathtouch, and can
attack this turn if it is your turn. You may switch
Sleeping Guardian's Power and Toughness until end
of combat.
