The Mistcaller may be the most over-budgeted card in TGT. Shaman decks normally run ~18-22 minions. By turn 6 you're likely to have 15-18 of these minions still in your hand or deck. That's on average +15 to +18 attack and health. It's otherwise a 3-4 cost minion. Meaning you are paying 2-3 mana for +15 to +18 to attack and health. Absurd value. I determined Varian Wrynn should have a 17-18 mana cost but The Mistcaller ought to have 17-20 mana cost. That means Varian Wrynn is +7-8 overbudget and The Mistcaller is +11-14 over budget. Crazy value.
