Thank you Funki for another fun deck idea! Initially I had a bad start with this deck, but after tweaking it a bit it feels quite strong.
I ended up taking out Dark Portals (too much of a win-more imho), Mortal Coils and Felosophies for more traditional QuestLock package:
1x Demon Seed (vs fatigue games mostly, once you run out of big threats)
2x Blood Shard Bristlebarks
1x Battleground Battlemaster
1x Mutanus (for lulz, but probably fast enough to eat quest rewards if it gets discounted).
Went 4-1 with a tweaked list, lost to an aggro pirate war. but I managed to beat a taunt druid. So far seems viable!
