Yeo burning is probelem, anyway they are too troublesome for no loss. And demonologist on scralet .. well possilbe but you will get them like once per 50,100 games?
Iits one of the rariest unit on the game. And i would like too see how it goes with them against big stack of dragons
Maybe timeback could save them .. but its posibble once per 2 turns actually . Would be hell to do that.
