Feedback request on Ghost monotype

Would love to get some feedback on this. Gen 8, monotype Ghost.

Some friends are getting together for a casual tournament just among us. Not looking to be competitive in the OU meta or anything, just want to see if this looks viable among the regular folk.

Input, changes, suggestions are much appreciated. Thanks!
