i have 1 titan card teh Blue dragon and 2 melee and 3 ranged... i use ghost armor/taurus warrior or ghost armor/ goblin. and for ranged i use fire succubus , centaur archer with the magic cannon. For skill cards i normally use. healing wave , comet shot , rain of arrows. and the phoenix (which probably the best Skill card to use) the last two are hercule's strength and Athena protection. i got all this stuff by beating a lot of stuff >.> :)
also i found out you get more mana as you complete more games... for example/ 1st game i complete when my dude hit 30 2850 mana... 2nd game 2900 mana, 3rd game 3050 mana , 4th 3100. and now i am on the 5th i have 3200.. kinda weird how it increases.
to beat the last challenge make sure to use white deck!! and use prismatic spring and global enlightenment you will win although it will take awhile.. (i won in 21minutes and did 56 damage the opponent did 96 damage to me ! lol)
