Felfin is much better than Felblade imo. Felblade feels awkward in many cases since the card needs to be in a corner, Felfin is much more versitale and reliable. All you need to do in order to activate this cards battlecry is to attack with your hero. You have tons of weapons in this deck to help you out with that and in worst case scenario you have to use your hero power which is 1 mana. 

Eye Beam is like backstab but it's not always free. Sometimes I find myself in turn 3 with little to play. Sometimes you can use this card without the outcast discount. This card can be used to target your own minions in though situations as well. Be smart and don't die!
