I've been using this deck for awhile and I feel it's power/influence requirements are fine tuned, but comments are always welcome.
Bannerman help get the right type of power.
Nocturnal Observer - Card drawing engine and drop units into the void for Haunting Scream
Poaching Drake - creature control, plus hits hard with berserk
Display of Knowledge - most versatile card in the deck
Great unit removal
Don't forget Display of Knowledge can permanently give a unit Quickdraw and +2.
All relics can be pulled with Display of Knowledge.
Speaking of Relics...
Infinite Hourglass - to handle permafrost, stun, etc
Dig Site - one time removal of enemy suck-iness
Xenan Obelisk always nice to have buffed units
