Ninja ... and imho it's not even close ... but it depends on what team you want to run at CB and for what level. 

ninja, no contest.

Would using both ninja and drexthar be viable for NM?

Drexthar isn't much of a Clan Boss champ, unfortunately.

Ninja however is just bonkers good. I forget if you've posted your roster recently, but could you toss it in here? Thanks. 👍

with this, you might try jareg, kalvalax, ninja, ghrush, and giscard. ideally, i'd want venomage in there as well (particularly with kalvalax) but i can't see any way to do that at the moment without either costing you damage or leaving your team extremely fragile.

ok. that might be in my future, but rn i only 6* champs that will help me everywhere bcz as a f2p player i dont have that much freedom. ill keep that in mind tho. thx.

fair enough. in that case i'd suggest same comp as above, but swap out jareg and ghrush for miscreated monster and vogoth. 

I don't like MM for cb, vogoth yes.  Jareg needed for atk down. 

I remember when MM was considered better than pulling a lego, champ-flation has killed him... 😆 

Could Ursala be used for atk down? Thats what i have rn.

i'm not a fan of him for cb either, but he's a lot more useful than jareg overall even with his diminishing value. for broadly applicable champions, mm is the way to go and he can be used as a stopgap until op can get jareg ranked up.

ursala can be used for now, but she's really not a great choice long term. she has a 2 turn atk down on a 3 turn cooldown, so it's difficult for her to keep it perpetually applied without someone else there to bolster it like jareg or giscard. she also brings limited value outside of that. her buffs are useful, but most of them come from her a3 which has a fairly long cooldown. most of them also overlap with giscard, who has both a shorter cooldown and a lot more overall value. the only real advantage ursala has over him is that she's already level 60.

i also think that she works better with defense/support masteries, which kind of eliminates her from being used in cb, but that's more my personal opinion than objective fact.

Agree with this. Ursula is actually excellent for hydra though you probably aren't spending much time there  :)  

as little as possible and still far more than i'd like to. been a while since i was able to fit ursala into a comp though.

Do you have lady kimi and kantra?

Counterpoint: Jareg is very likely going to be a staple for you in Faction Wars and has some applications in Doom Tower long term (namely Eternal Dragon)

Very likely to be in your Clan Boss team for a long time too. 

no. i wish. but no.

ahhh you have me cornered huh?? k. ill do him after Kalvalax and maybe someone else. i dunno my order im gonna build champs.

:)

just offering an alternative take. all good either way.
