After playing Hemet, Jungle Hunter and erasing all cards in your deck, play a Target Dummy or any 1 mana minion (if planning on winning on turn 9 or 10). Then use Shadow Hunter Vol'jin and switch out your 0 or 1 mana minion which will be replaced with your only other minion left in your hand– Mecha'thun. Then play Cataclysm with 4 mana remaining.
WINNING TURN 8: In order to win on turn eight, you must have the coin. If you were the first to act, you cannot win on turn eight. You must play your combo with Target Dummy as the minion to be replaced by Shadow Hunter Vol'jin. Play your coin at any time while activating this combo and then use your remaining 4 mana to play Cataclysm.
WINNING TURN 9: You can win on turn 9 without the coin, as long as you have kept a Target Dummy. By using this 0 mana card, you will only need 9 mana to complete the combo. You can also use a 1 mana minion instead to play into Shadow Hunter Vol'jin, and use the coin in order to have 4 mana to play Cataclysm.
WINNING TURN 10: All you need to remember is to keep ONLY ONE 0/1 mana minion in your hand when you play the combo.
This Mecha'thun deck works great because of all the 1 mana cards that can be destroyed by Hemet, Jungle Hunter, which gives you the opportunity to win very early game. Be careful of Spell/Secret Mage when playing this deck, as well as any Rogue decks that may force you to draw cards or manipulate your deck, as well as many Priest spells. Here are some cards to be wary of that may just ruin your game...
- Mutanus the Devourer
- Coldlight Oracle
- Bad Luck Albatross
- Mindrender Illucia
- Psychic Scream
- Shadow Hunter Vol'jin being played by opponent onto your own minion
