Step 1: get as mush income as possible, I used 10 goldmines, 3 dark merchants, 2 dwarven mines and 1 dwarven bone, after clearing the deck I had +35 gold at a second. Also 2 iron mines and crystal mines will suffice.
Step 2: Use golems, scouts and variety of mages/archer you find useful. I also found fire storm incredibly useful (used 3).
Step 3: Get and income of atleast 9-11, get some units to hold the enemy, upgrade to 15-19 and build some more units to hold him. then clear your deck and save some money. you are now good to go, blast the opponent and win.
You most probably won;t win with 100 health, but you WILL win using this method.
Protip: You don't have to use 50 cards when building a deck.
Hope it helped anyone.
