Moloch is very fun, but it’s a lot of traits to spend if you don’t have a more synergistic deck planned. Speed and souls is something you cannot let go easily.
If you replace Druid you should do it paired with Valkyrie.
You are then left with;
Jarl Firemantle
Eternal Flame
Moloch
Would you keep the positions and put Moloch 4th? If so, then what we can start thinking about is a replacement for the 3rd slot.
ADDED LATER:
I missed the post about you valuing Valkyrie highly, but I’m leaving what I said up in case you are open to replacing her.
If you are intent on keeping Valkyrie, you should consider replacing Eternal Flame when you acquire Moloch. My instinct would be Serpent, a red Gem generator that feeds off Blue, which Valkyrie provides. Serpent also poisons 2 Troops at once and gains Life with each cast, with also being one of the few Troops with Agile (3rd Trait);
Jarl Firemantle
Serpent
Valkyrie
Moloch
Mist of Scales Banner (Red/Blue)
Synergy-wise, Air Link is awesome for getting the Hero and Rocket off the ground. Personal preference-wise, I actually prefer Sorcerer in general, but it doesn’t benefit this team much because nobody cares about purple and because Eternal Flame doesn’t scale with Magic.
Ah, missed the follow-up. Good point – this team isn’t well-suited for Valkyrie. Personally I don’t think Jarl and Valk mix well, because she stomps over colors he cares about, but some of the other suggestions in this thread seem reasonable.
Thanks everyone for your suggestions, I will probably forgo eternal flame and go with Jarl, Moloch, Valk, Acolyte and see how that goes. If I can keep the same speed and winrate doing so I will be so happy.
