Blitzscream

The ideal plan with the deck is to swing with a berserk pumped disciple, occasionally this will be a turn 3 swing for 24 (gift + rapid shot), more often several swings with pumped berserk units. It’s generally best to wait until the opponent is tapped out before committing to a big swing, so this might be later in the game, and sometimes it’s a unit returned with scream, especially against removal piles. Timing is everything with this deck, identifying when to trigger berserk, when to pump, and when to go for a giant lethal attack.

Sequencing of units can help bait out removal, dusk raider is great for drawing fire so your elves and disciples have the best chance of survival.

You rarely use finest hour/quick draw to trade with an opposing creature, unless it is something you want dead or you get 2 for 1 value; try and save them for a lethal swing later. Sometimes it is worth a single pump on a berserking unit if it kills a blocker then hits the opponent for a bunch.

Merchant usually fetches gift or scream, especially if it is my only turn 3 play and there is no clear card needed (if in doubt I grab scream). I often merchant away my 4th power as the deck can operate on 3, only needing 4 or 5 for combo turns involving scream which happen later so you usually draw in to it in time. Permafrost is for cheaply removing a blocker. Lightning storm vs token hordes (over hailstorm as our important units survive it, but this might be wrong). Changeestik is usually just for the evasion and pump, but I have spell crafted a few times (hitting an SST with it is so satisfying). Could possibly do with a unit in the market but not sure what I'd cut for it.

Thief’s pick mostly works out well ensuring a berserk unit can get in, and again on subsequent turns once relentless. A canny opponent may leave a flying blocker back to stop a surprise scream getting them, and the unblockable gets round that. Possibly ghostform is a better choice for cheapness, but it feels a bit more all in; it's not unusual to put it on an aegis unit and get in for multiple turns. It rarely gets spellcrafted.

Update: Really liking the pacifiers over the battlemages, they dodge a lot of removal and flying plus overwhelm is good with berserk + pump. Switched the picks for ghostforms, which they probably should have been anyway.
