This deck is trying to make fun shenanigans out of spirits. You apply pressure early game by using Headless Haunt, Gyre Hippogriffs and Castle Haunt. Mid game you use Thunderstorm, Abundance and Atlantean Fate for damage, ramp and removal/control.

Late game you use your Ghost Ships and Ultimate Horror to get your spirits back from the graveyard and keep the pressure going. Magic Missile and Lightning Bolt for small removal and late game kill-ping.
