Hey Goldridder5!
Deck Setup:
Have 2 frontline units (knights or drogon riders, if not then zombies and goblins until then) the rest ranged (dwarven eng, witch, succubi, archer, cannon). Upgrade your cards for the ones you use. My final set up at the end of 3 full games and 2 challenge levels looked like archer, witch, succubi, knight, drogon rider, cannon with spells comet, raid of arrows, heal, lighting bolt and hercules strength.
Strategy:
I start out by pooling a small amount of forces in the middle then sending a comet shot over to their hero unit. Once he's down I start on the other side with everything. The entire time the upgraded comet shot regens quick and is used to take out stuff clogging your front line from moving or trying to fight back the creep at the side of the map. Watch your hero, don't let him die. If you stop making progress on the other fort regroup to the center of the map for more forces.
Has a very rough\laggy feel to it. Had no idea which way the creeps were coming in the first level before I hit the start button. Needs a lot more polishing 1/5
When a wave isn't completely finished and you press the next wave button, you do not get the 10M bonus for clearing the last round. Needs a wave auto-start feature and a fast forward feature.
