Definetly not Relickeeper, who is offering absolutely nothing usefull at CB. Maybe he actually deals damage if you have Wamaster on him, but any lvl 60 champ could do the same. 

Hope could be good, because her shields offer some usefull defense to the team. The shield is based on her HP, so she doesn't perform well because she is only lvl 50. Make her lvl 60 and use euip with main stats that fit (hp-%).

You should use a champ with atk debuff, that reduces the damage of CB a lot and gives you some extra turns, one of the most usefull buffs/debuffs at all in CB. Replace Relickeeper with a champ that does that on the long run.

The  only  reason i  have  relic keeper  in  is  because hes  one  of  my  hardest  hitting  and  one  of  the  first  rares  i  got.  Hes  just  holding  someone elses  place  i  just  dont  know  who  yet.

You could at least replace Relickeeper by Cupidus, who will put some HP burn in addition to serious damage. 

Using High Khatun could make sense too, especially if you put her in the lead spot for her aura. Although not sure if that would be an upgrade over Hope - Skadi is right that you really need decrease attack and until you get it, you'll die sooner than you should, so maybe you can't afford to lose Hope at the moment. 

I have a Spicy team you could try out:

- Coffin Smasher

- Warmaiden

- Kael

- Seeker

- Fahrakin  the  Fat

You would need them all in Lifesteal gear though.

I  just  pulled  apothecary should  i  replace  someone on  my  team  with  him?

If you just pulled hi: no. But when he reaches lvl 60 and has Giantslayer masterie skilled: yes, replace Relickeeper.

/edit: If you are talking about replacing somebody from the team Player J recommended: Replace Warmaiden. I don't know why she is in that team anyway, Fahrakin allready offers decrease def on his A1.

I  recently  pulled  apothecary and  sepulcher  sentinel . i  Am  currently working  to  6  star  one  of  them.  what  one  would  be  most  benifical  to  six  star  first?
