My team last time:
BK is maxed now and has some emblems 
So the whole team looks like this:
Was smooth again - Gretel to prevent Elena fire her special and the rest to take down those DoT-types, no problem at all.
Now to the harder questions:
- Barbarian emblems: BK is now on node 6
- Fighter emblems: stocked for some worthy candidate. Boldie is maxed out. Hu Tao is lame. Colen is on 3/60 and Misandra and Elena are waiting for a decision
- Trainer hero: another good question, I think he would be wasted on Ei-Dunn? Maybe Colen will get him, once he’s on the next ascension tier…
