Yari Mini-Sub

Bushido 1 (Whenever this creature blocks or becomes blocked, it gets +1/+1 until end of turn.)
Sacrifice Yari Mini-Sub: Destroy target creature with power less than or equal to 3.
Its pilot, loyally bound to his Emperor, is prepared to use his craft in a battering maneuver known as the "Last Voyage", which can severely damage even the sturdiest hull. This destroys the Yari mini-sub in the process.
