Perhaps I'm just missing them, but I'm not seeing someone who can put up a team wide counter attack buff (Skullcrusher, Valkyrie, or Martyr). Without 1 of them and a spd tuned team it'll hard. That being said you do have some good pieces, Frozen Banshee is a staple for most teams, and Norog is a great stun tank as the leader (though you'll lose out on an aura). 

When constructing your team, you'll want to focus on people who can bring these buffs/debuffs: Counter attack, atk down, def down, and weaken. Then having a healer is nice but not always necessary if you have a consistent leech debuff and/or lifesteal with tier 6 masteries. On top of that you'll want to have 1-2 poisoners, Frozen Banshee being great for 1.

And this is all assuming you aren't running an unkillable team, which is additional considerations I won't get into. 

Hope this helps.

Yes you are right, I don't have a team wide counterattack :(

I was hoping for a way where there are high speed poison heroes needed who do the damage. Something like: high khatun, lightsworn and 3x frozen banshee?

Maybe there are other ideas which I could try. I need 1 hero for rhazin would that help me?

I think your best bet is ally attack team.

Kreela with as high speed as possible.

FB, Zavia for poisons. Check how many you need to fill debuff slots. 

Lightsworn with booked A2 going 1:1 with CB and placing Atk Down for 2 AoE turns.

With godly gear it can be 2-key, but 5-key is more likely.

I'd go with a speed team probably like Norog lead, Arbiter/Sethalia, Kreela, Frozen Banshee, Rhazin (after you're done with him). Good luck, keep us posted with the team's progress! 

Thanks for the ideas guys, I have tried it with Kreela but it wasnt so good because it's lvl 50 and not booked. 

I went for another team and it does not look so bad. Probably I need more speed and better gear to get it from 15m to 18m damage. 

i

you dont have it bro, keep playing and keep pull shard for a better champ, like top tier epic, and top tier lego. stick with nm or brutal for now.

Kreela is good choices. She can attack enemy + boost critical rate and trigger allies attack. My old team was Tayrel, apothecary, foli, occult brawler, kreela. I can get 18-20 M on neutral affinity. 20-22M on green affinity. But on red affinity the score is very low. 

Cool I would be happy with 18-20M. Is your kreela booked or it does not need to be?
