My own Strategy to the challenges... May look like the own that has 3k votes but trust me i played the challenges several times and this is the most efficient.
Challenge 1: like said above use Sky Dragon.. And Meteor blast to take care of C
Black imps. For units your choice. But it is good to have Popo as a hero/ or Simon since he freezes.
Challenge 2: Have Popo to take out bombs make sure to have shield up before it blows. And have time stop to slow them down.
Challenge 3: (Normal) Charge him with units try to arrange him so he is facing away from your base so more troops can come in (Hard /Epic) Use Sky Dragon to take him i tried all the other titans he works the best. Make sure that their shadows are touching so he does not die. Use shield so he gets there safely, Also use +100% crit / +100% attack so Baal dies faster and do not be afraid to use meteor blast it deals a bit of damage to Baal 5000-6000 if you have +100% crit / +100% damage.
Final Challenge: (normal) try to aim the angel away from enemy base meanwhile attacking it with troops. Pure melee troops i suggest. Power ups Shield and Time stop. Final Challenge (Hard): Now this one you want to do an immediate charge expect your heroes to die. Once when your heroes are up charge again and try to make your troops attack the castle meanwhile goblins/ Dwarfs are hitting Lord of fire. Make sure to use shield so troops do not die. revenge waves may kill your troops so also have a titan to stop the revenge way from getting to your base. Final Challenge (epic): Just charge base use shield once when it is up and once when Yeti is above you just keep attacking and the castle should go down.
this is a challenging game but not hard to catch on to controls. i wish that maps that require a certain player isn't on a totally different map. you need "letter f" for dunes yet you unlock him in planetoids. just saying.. also this game would be great online you make own biker and create own bikes and maps and buy horns to honk at other players would be fun.
i hate how all your dudes run all the way to the goal point the opposite team's goalie has the ball. should they charge him instead of running the other way?
are fücking kidding me seriously 1% left and all of the sudden i am dead cuz soem how the goblin hoped over my guys just dumb he should be fixed.. idk but either it is bad luck or just a dumb glitch it shouldn't happen.
also the goblin isn't invisible it is simply faded and is hidden by that weird horse riding dude so refrain from attacking him so you don't have to lose!
why are ppl complaining about mass spawns of enemies thats why we have skill cards... USE THEM when most needed. DO not use them right away cuz you lose like that.
