Fun Game. Easiest Way to Win. Keep only your gold mines, the dark merchant and all your cheapest units in your deck. Just keep drawing cards and playing your mines until you have used them all. Put 5 of the cheap units in the summon slots and wait until your gold is at about 300. Then spam them all. You should be sending 50 units to the enemies gate. Each one does 2 damage. 2x50=100. Just in case put up another cheap unit and send all ten of them. Also, play the dark merchant as soon as you can. You can modify this deck with coin purses or more cheap units, but be sure to keep the gold mine ratio balanced. Good Luck!
