Brace Yourself, Wildfire Imp, Flank Attack, and General's Signet Ring are in a video review up on BGG:
http://www.boardgamegeek.com/video/46888/mage-wars-forged-in-fire/drivethru-8-drive-thru-forged-in-fireBrace Yourself: level 1 war enchantment, Novice, 0 to reveal, Armor +4, destroy Brace Yourself at the end of the round.
Wildfire Imp: level 1 dark creature, 5 mana, 5 life, 0 armor, 1 die attack with Piercing +1. Instead of moving, you can pay 1 mana to teleport to a target zone with an object with a Burn condition on it. Wildfire Imp gains Melee +2 while attacking an object with a Burn condition on it.
General's Signet Ring: level 1 war equipment, Warlord Only, 3 mana, once per round when you or a spawnpoint you control casts a soldier spell, you get a discount of 1.
Flank Attack: level 1 war incantation, command, 3 mana, targets a soldier creature. It's a little hard to make out the wording, but I believe it makes a soldier attacking the same target as another soldier attacked that round get Melee +2 and Piercing +2 for that attack.
