I am compiling a list of the fastest ways to kill the opposing hero in Hearthstone. This assumes that the other player does not change their health by armoring up, tapping, or any other means. Also, the opposing player does not play any cards, so wins with Millhouse Manastorm are not possible. Assume the player has the Coin.
Here are three 3-turn solutions I have.
Turn Card(s) played Damage dealer(s) Opposing hero health 1 Coin Dust Devil Dust Devil 30 2 Dust Devil (6) 24 Dust Devil (6) 18 3 Rockbiter Weapon Rockbiter Weapon Dust Devil (6) 12 Dust Devil (18) -6
Turn Card(s) played Damage dealer(s) Opposing hero health 1 Mana Wyrm 30 2 Sorcerer's Apprentice Coin Frost Bolt Frost Bolt (3) 27 Ice Lance Ice Lance (4) 23 Arcane Missiles Arcane Missiles (3) 20 Mana Wyrm (5) 15 3 Fireball Fireball (6) 9 Sorcerer's Apprentice (3) 6 Mana Wyrm (6) 0
Turn Card(s) played Damage dealer(s) Opposing hero health 1 Young Dragonhawk Coin Cold Blood 30 2 Young Dragonhawk Cold Blood Young Dragonhawk (10) 20 3 Young Dragonhawk (10) 10 Young Dragonhawk (10) 0
And a 2-turn solution.
Turn Card(s) played Damage dealer(s) Opposing hero health 1 Target Dummy Target Dummy Innervate Innervate Mimiron's Head 30 2 Crazed Alchemist V-O7-TR-ON (32) -2
Can any of the above be optimized further? Also, what are solutions for other classes? (I suspect Murlocs may be involved in at least one - I have seen a video of a 4-turn Murloc victory.)
