takd champion out. put in nija and immortep. this is because champ is only good for boss fites. ninja hax a high proc so ninja has better atk. ninja attack fast too. switch champ w ninja then add immortep because of its sick ability, its releability and its better optomization. if u need help reply back.
Add immortep now, drop champ asap. add ninja for 6th base until you get cupid. I would suggest using reaper instead of snowzilla too. Immortep is way way strong in hbm and raids. ninja is way better then champ in raids and hbm as well. Champ has super low hp and just dies too fast, he is only good for stunning boss.
I would add ninja and Immortep and drop champ, use him for an alternate.. He's a total weakling who dies even more than ninja :)
Immortep tho has gooooottttta go in your troop, like now.. Play him for a bit and you will see he is a total beast man.. Like 5th best hero in the game.. Better than snow, champ, ninja, once you get some play time with him you'll be a believer.. I love Immortep.. I just got him 3 weeks ago, I've got him to 4/9 and level 106, and my god everything just melts around him as he walks down the path or whatever... He just annihilates everything..
