developer i liked your idea of giving to races why i have wrote read this:
when we complete 1 of them we are thorough with most of cards battles and evolvutions so if we have other campaign it becomes complicated and it makes it exciting.
if u didnt do it we would be bored to do one same.
the ones which dont know how to evolve read this : when u start the game
after all selections there is a list on the corner eg demon warriors :lizard recruit>lizard warrior and ahead so when u battle if u have cards according to the list place a lizard recruit and if u want to evolve it place lizard warrior card on it its stat increase [it actually evolves] lizard is just an eg u can do with all according to the list thank you give+1 if it helped u.
i have some ideas: to the developer
when we evlove a card the picture doesnt change please fix this problem i hope u will appreciate my idea.
a good tip if you want to keep your units spamming then if you no that your hero can die so keep hero near castle and if units cant stop them if the enemy units came near castle heroes will attack them and kill them and angel is best for dealing damage but medium in health lord of fire he goes foward while attacking and he is a good attacker and nice in health dragon is best in health but weak in damage and for diablo i can only say one word he is a big meat shield after all dont bother this titan
give a + if it helped you
Extra 8 Stage; The Inferno
It’s that annoying spinning efreet thing that goes tornado mode to destroy all your units. Keep sending melee distractions and build walls on him to slow him down while your archers do the damage. He will probably get really close to your hero before dying.
Need; walls, stuff like Goblins, tons of archers
Don’t Need; strong melee units won’t last much.
Units to Take; cheap and fast melee units, Centaurs, Elf Hunters, Mages
to defeat the collosus he is very slow so ranged units goblins or fast spawnning units and white tiger[wolf] so goblins will slow the progress of the collosus and your ranged units and white tiger[wolf] will attack him and use wall skill here a lot warning he will get very close to your hero before dying and his attack does nearly 5000-10000
