The Princes open up so many deckbuilding possibilities absolutely nothing wrong with them. Blizzard have even mentioned they plan out sets 1-2 sets in advance so who knows what will be introduced in the next set that could make the Princes power levels insane. Saying Taldaram is a joke tskk tskk have you seen Aviana, Kun the Forgotten King, Malygos, Faceless Manipulator, Prince Taldaram in Wild? Having an extra copy card is great for consistency sake, also an argument for it being in Big Priest over Mirage Caller as someone mentioned is because having Mirage Caller die pollutes your Eternal Servitude pool whereas Prince Taldaram does not he becomes a copy like Manipulator so when he dies he is still the copy he died as.
Ok thanks I didn't realize that. That makes sense then.
Keleseth see's play in zoo decks, Valanar see's play in rogue decks and I have been playing Taldaram in wild with my own big priest deck and is over 70% WR. So no they aren't as bad as you and many others thought.
Yeah the Princes turned out to be much stronger than people expected. But why would you run Taldaram over Mirage Caller though? He has greater stats and is immune to Potion of Madness but is it worth sacrificing Shadow Word: Death for?
