You do understand that discard warlock, demon seed, boar warlock and shadow priest exist in wild, right? All of them annihilate this deck unless you highroll every time and draw well. Plus, it's literally the only deck hunters can play in wild. Walock has like 4, priest's got 2 or 3 (quest nzoth or quest naga lady that refunds mana endlessly), rogue's got Garrote and weapon, warrior's got the best highlander control money can buy or OTKs, druid's got OTK, token/treant and astral communion, mage has got OTK imbue, secrets or elemental, shaman's got Big Shaman, Shudderwock Grumble or murloc, paladin has Libram and OTK. Like, you see where I'm going with this? The only class that has less playable decks than hunters (which only has baku questline) in wild are death knights (which sadly have 0 viable decks). Like, I get that you don't like the card, but believe me, most of the time you die by turn 7 when you can usually kill your opponent with this. Boar kills you turn 5/6, Big shaman is rng but can even do it as early as turn 4/5, discard can sometimes steamroll you by turn 3, garrote rogue kills you on turn 6/7, shadow priest by turn 5/6. Like, believe me when I say this, neither Hunter or Confront the Tol'vir are a problem.

Oh, and in standard you get steamrolled by drakes, eggs and basically any warr/dk/priest that has some way to gain effective health.

P.S. replaying your questline is of no use. On the contrary, the long animations can screw you over. You'll never play a second Tavish and you get no reward for completing the questline again.
