The rules for
Deploy are included in the booklet that comes with the YV-666.
After the Hound's Tooth is destroyed but before it is removed from the table, you declare either to deploy from the front or rear guides of the YV-666, you choose a maneuver on the Nashtah Pup's dial, place the appropriate template on the declared guide, place the Z-95 at the opposite end of the template (this counts as executing a maneuver), if possible, you may perform one action.
