Basically this is a control deck (i.e. you want to react to what your opponent is doing and what kind of deck they are playing)
Permafrost should be used early as possible as it can later be combined with
Felrauk's Choice to get it back. If your opponent is Aggro use
Timidity on their most dangerous or hardest hitting threat to neutralize it. If your opponent isn't doing anything bring out
Unkindness as early as you can to give you some blockers or threats.
In the midgame you have
Tidal Forces as your main way to attack (similar to a
Phoenix Stone). The only units I have included is
Archgryffyn Patriarch for card draw and
Feartracker to gain life. When you get two units out (or one actual unit and the Tidal Wave) you can use the
Fearbinder relic to make a huge Berserking threat for your opponnent to deal with.
The rest of the stuff is pretty self explanatory.
Avigraft for big grounded Endurance threats,
Numbing Cold for other Control and Spell based decks, and
Succumb for any Unit (Aegis, etc) that you can't otherwise deal with.
Honestly, I wanted to include a market but the Justice one seemed the only useful one and you would probably be putting
Fearless Crescendo on your opponents units and not yours since the deck has 8 units and they both cost 5.
Anyway, comments or suggestions are appreciated!
