Reached masters with this from Gold3-Masters in around 5-6 hours.
i have not crafted any of the cards and would recommend the deck be played as it is, the only change you could probably do is replacing fearless yeti with champion of fury, but i made it without it so you dont need to craft it, fearless works just fine
Notes while playing:
+dont hold onto entangling vines just to get value, if need be use it on a single troop to get some damage in.
+when you see Primal(Hail Storm),Shadow
Devastating Setback or Justice
Harsh Rule you need to play conservatively(have no more than 2 units out) because of the potential sweeps. a good play is just dropping 2 grenadin drones to bait it out, if he doesnt give in you can rally them for a good chunk.
+always expect to lose your dusk raider, dont play around it giving berserk but play around it being removal rod, countless time i have been able to play crunch safe because i wait and play dusk raider to check for torches.
