Easy way to win card challange.
Use Red 2 x Commander A=J'Arden
use Red 3 x Footsoldier Elite
use Red 5 x Footsoldier.
The Elites and Commander get massive bonus if you have more soldiers in play. 2 Commanders can easaly turn into lvl6 units with minimum of mana usage if you spam elites and footsoldiers.
Game is very easy if you DO NOT WASTE EXP on upgrading total amount of mana in the skill screen. This is because mana ingame is limited to a maximum of 9999 and each mana upgrade doubles regen. However the skill screen version does not double regen so you are stuck with 9999 afer waiting forever for upgrades.
Its beter to keep default of 20 mana and upgrade that ingame as by the time you hit 9999 limit, your regen is so high, you can spam dragons forever and still fill up like mad!
TOO MANY BUGS. Game Glitches after people buy stuff, even the surrender option does not work. When game s working again, I expect it to be great. Till then its a waste of time
Take your time. Once you get to 50 or so, then the game changes to a space invaders version where you need to catch them yoruselves.
It takes longer to get to 50 than it does from 50-150. Its easy if you take your time.
Thank god no card trading. Otherwise players would trade crap cards to newbie players for their good one. Nobody would want a crap card therefore card trading would only be scams
game is easy if you do a clockwise direction around your starting poinjt. Remember that the further you go from start, the harder it gets so you can almost max out in starting area if you orbit it
