Mtn King is a 6 star for sure.. although maybe not for CB.

Achak is worthy of 6 too for.. again not for CB though.

Rhazin is a good 6 star bet for CB if you don't have Venus or Dragomorph. If you have Venus or Dracomorph.. Rhazin isn't going to be "better" there.

If I was stuck with these characters.. I'd replace Jarrg with Sepulcher for CB.

Yeh i wouldnt run MK or Achak on CB for sure. I honestly cant see where i will use MK though?

I have draco and use him for defence down/ weaken and poisons...i could just straight out swap Jareg for sepulcher, but given how often my runs end due to attack down failing i was toying with running both.

M  Mage  is  well   known  for  Dungeon  Speed  Runs.

M  Mage  +  Seer  Combo  is  highly  sought  after.

Seer  does  more  damage  when  she  removes  buffs.

M  Mage  adds  tons  of  buffs.

Only  Recently players  have  been  shifting  towards  Lydia  +  Seer  Combo.

Lydia  is  Faction  War  hero  reward  you  get  for  beating  all  Factions.

Lydia  does  several  buffs  +  def  down  +  weaken.

It  comes  as  no  surprise why  people may  shift  towards  Lydia  over  M  Mage

However,  if  you  don't own  Lydia,  M  Mage  is  top  of  food  chain.

A  Epic  Champion  fairly  accessible  which  combos  very  well.

Despite  M  Mage  fame  with  Seer,  M  Mage  has  remained  Humble.

M  Mage  has  proven  himself  to  be  highly  effective with  out  Seer.

Players  have  used  M  Mage  in  the  dungeons  with  out  Seer  based  on  his  merits  alone.

The  Ability  to  Increase  Defense  +  Block  Buffs  +  Cleanse  +  Heal  can't  be  over  looked.

Ice  Golem  &  Dragon  are  2  dungeon in  particular were  M  Mage  Abilities  Shine  Thru.

In  Addition,  M  Mage  has  also  made  appears  in  the  below  locations:

-  Faction  Wars

-  Arena

-  Tag  Arena

-  Doom  Tower

-  Clan  Boss

------------------------------------------------------------------------

Despite his  small  appearance,  The  M  King  has  proven  to  the  world  he  has  BIG  Heart.

M  King  determination  &  effort  has  lead  him  to  be  highly  sought  after.

M  King  most  nobly  known  for  his  Arena  prowess.

Their  isn't an  Arena  Team  alive  that  shouldn't be  scared  of  this  little  guy.

He  is  the  King  of  Arena.

I  wish  I  owned  him.

He  opens  up  alot  of  Go  2nd  Team  options.

I will take another look at mausoleum mage thanks, he was the last one i was considering. 

I dont want to change my dragon team, poisons still work extremly well and zavia with draco just blows dragon up really quickly.

But golem is a nasty one for me so worth looking at.

As for mountain king, its odd- my own experiences are one thing, just today i got soloed by a mountain king, i had nuked the enemy team and he was the only one standing, and then he proceeded to just whack my team one by one....even when i provoked him his A1 one shotted me!

But the guides suggest he is very hard to gear well enough to be effective.

All  the  heros  you  mention  are  6  star  worthy.

It  just  depends  on  what  your  looking  for.

MK does need a lot... but then he also does a lot. Mine is in a shield set, which is part of the reason that I still didn't manage to get him perfect crit rate - not without losing too much speed/HP/crit damage, anyway. And of course he'll always fail to crit at the most inconvenient times. Nevertheless, he boosts team survivability by a lot, he's hard to kill himself and does a ton of damage - that's great not only in arena but also in FW and DT. 

As for Rhazin, you don't need him on CB as you have Draco, but do keep in mind his AOE Turn Meter reduction, as well as the arena resistance aura. I don't often use him in regular arena, but certainly in TTA, he can be very effective with that aura and that TM reduction move, doing a lot of damage in the process too. 

And the rest, honestly, all six of those champions are worth 6*. 

Thanks guys, i am going to focus on sepulcher sentinal and try to fit into my clan boss team- she might also make knight revenant my second completed FW team as well as she is perfect for what i need there

The recent arena changes have made it less urgent with my arena teams and i would love to be able to 1 key NM (im close but its hard without counterattack) 

Thanks again
