Because it follows the latest Hearthstone trend of no counterplay . Before Naxxramas , every card used to have a counter however , since the addition of deathrattles , the nerf to silence effects , and especially the introduction of N ' zoth , the game no longer rewards you for skillfully building your deck to counter specific matchups . N ' zoth is the best example of this design flaw , being a card that always generates card advantage and singlehandedly nullifies some classes without reliable board clears , like rogue and has no true counter . at least Dr . Boom was weak vs lightbomb and brawl , shredder could occasionally pop a doomsayer or a 11 , mad scientist can be silenced , deathlord can be cabal ' dThis is the reason why I think Jade Idol will be one of the worst HS cards ever created unlike other cards which offer huge value at the cost of temporandomnesssafety e . g . thistle tea , burgle , rafaam , jaraxxus , dreadsteed and many others , it provides infinite , exponential value for 1 mana , in a class which has already so much drawing potential , multiple removals and ways to stall the game poison seeds , tree of life whilst cheating on the mana curve . Besides the little detail of having absolutely no counterplay , of course .
