With Standard bringing a new way of playing and some fresh air to the game, also come the fear of the fear of losing some cards, and i believe could each year add a couple class cards from the rotating sets in the standard roster, while this being a dangerous move i believe they should only add cards that somehow became a part of the class identity and not cards that are usually powerfull in that class, one example for this is Quartermaster that is a card that is not considered as powerfull it can still support paladin hero power and then being a powerfull card to support the identity of the class, on the other hand a card like Lightbomb for priest even being too powerfull is a must of on the class and then needed to be added to the current roster to make the class on par with the others.
Here are the cards i believe could be added that would not in any way make the class stronger and still would make the identity more clear
This card being powerfull and somehow supporting the class identity not being too powerfull unlike Muster for Battle
A card that pretty much is a must for a priest deck and the only comeback mechanic before the standard and fixed on the priest history
With Blizzard trying to push a Beast for the Druid class, this card being on the standard roster could be a great way to make the deck viable
Those 2 cards seem good on mage and pretty much used across most of the mage decks
Not much need to say since GVG and Naxx didnt bring any staples for shaman beside crackle and that is not a card that should be on standard
With blade Fury gone i dont think this card woud be used but beside this the only other good card i can think is Sabotage and i dont think people would use that card either
Voidcaller might be a very powerfull card but that is the main enabler for demons and with blizzard saying they are going to print more of then this card would fit the theme and enable more powerfull demons decks and maybe someday people stop the zoo madness, now darkbomb is not as powerfull and probably a very important card for control warlock decks and that would be a very nice on standard roster
the other alternative being Death's Bite and warrior with another powerfull weapon it would become the most powerfull deck around and we dont need that and shieldmaiden a powerfull card but not overpowered in any sense
those two cards being used on most hunter deck that could fit very well on the class flavor for the future
What you guys think about this idea, and got any suggestions?
