I would like to see it, rather than creating a 5/5 copy, pulling the card out of your deck, putting it on the battlefield as a 5/5. As it is, it’s absolutely insane in the big resurrection priest deck that I’ve been playing against every 2nd game for like 3 years because it hasn’t been nerfed even once. Auto loss for me vs the priest deck that never leaves the meta every time because if you don’t kill them in 5-6 turns or have a 1 turn win combo for later, it’s just over once they get their first big unit out, especially if that unit is blood of G’huun. Never ending 5/5’s with 8-9 cost unit effects at the end of every turn endlessly? I just had a game where I went til I had 1 card left in my deck but he had 10 still because G’huun doesn’t make his cards run out.
rez priest has always been t2
why do you think it costs 9 mana ??
People play it on turn 5-6 in wild.
They need another tech card to put bad minions into the opponent’s deck. One more card similar to Albatross. It’s currently tough to interrupt big priest.
People win in Wild on T5-6.
pretty sure we will soon. I mean we now got BigMurlock. as a additonal option as handdisruption(other then rat). Another for decks is a matter of time.
Well you just called 2 out of 3 of the main playstyles in Hearthstone(that are also the most common when it comes to wild). So rez is countered by the big part of the meta decks.
Zero:
Start of game: shuffle 3 random 1 cost minions in your opponent deck…destroy this card after the shuffling and increase the cost of 2 random card in your deck by one(except 10 mana cost cards)
there your big priest answer 
your 1 card closer to fatigue than your opponent…2 cards of your cost 1 more…but you get to mess with opponent deck
