Care to explain why it's the most cancerous deck in history ?
I still have bad memories of pre nerf starving buzzard beast hunter, and pref nerf undertaker face hunter.
Pirate warrior with pre nerf patches.
Aggro druid with pre nerf force of nature, that 14 health threshold that you had to maintain at any cost while clearing the board every single turn.
And more recently secret mage in Wild is giving ME cancer. You just lose if you're not playing a t1 deck with an insane opener. There's just too much consistency, synergy and mana cheating in that deck for my taste. And the anti secret tech that is just so slow and barely improves your chances while ruining your deck against other classes.
And these are just the aggro decks. I won't go over cancerous combo decks but I could.
Nowadays Hearthstone has a little more tools to deal with the insane aggro openers.
Priest and Warrior with their efficient, low cost board clears and numerous healing cards will destroy this token DH deck.
Token decks can be very powerful but also very polarized and susceptible to counter decks/cards in my opinion.
In fact I think aggro DH with all the token synergy replaced with weapons and hero attack buffs and cheaper cards will be much harder to deal with. Wrathscale Naga is very clunky sometimes and without this card the decks barely does anything. And feast of souls while potentially game breaking I'm sure you found out is hard to include in a deck and can be sitting in your hand for a long time (I see there is only one in the deck you linked, doesn't surprise me) aggro DH needs cheap, direct damage, and cheap, direct card draw, not combos. And he has a ton of that. Cycling through your entire deck with Altruis will be crazier than turn 8 Wrathscale and Knife juggler shenaningans I think.
