Finally found some time to play this month and reached top 500 with my favourite deck, a classic Questline DH list; don’t know how much time I have to keep grinding ladder, as I have a dissertation to submit lol

Really strong deck that will play a malicious board game, which is your plan A. A common mistake people do on ladder is pushing for the fatigue combo. That’s your plan B. You’re essentially a structured miracle deck with disruption.

Your left hand side is your contingency plan. Your right hand side is your immediate-plays/opportunities. That’s how you manage the outcast mechanic.

Vs Aggro you either spam Brutes or lose.
Vs Egg you’re looking for Consume Magic, either draw it skilfully or generate it (also skilfully)
Vs Boar, you mana burn them before their key turn, and you Glide them all day

Reno decks can AoE your board, then rat your Aranna, then Zephrys your Glaivetar. Again, mana burn and Glide are your best cards.
Hostage mage will freeze instead of destroying your board, blocking your game progress
Dungar Druid has a ton of outs vs our disruption
