RiftWing + Byzantine Kitty is a great combo for a Lost Magic Ruleset.
Watching riftwing gives damage to the attacker using backfire ability. Fun to watch no attack monster but can kill the attacking enemy. Will definitely play more of this combination in lost magic ruleset. If its a high mana game, add more speed (swiftness) or slowness on your opponent will definitely increase the chance of dodging the attack and backfire will slowly kill the enemy.
