Eternal Brews - Funstable Berserkers, iterated to my taste.
Budget Skycraggro with a fun twist - the plan is to trade half cards for a cards worth of value, as a bonus you rarely get power flooded as excess power trades in as well. There are plenty of interesting choices so it's a lot of fun to play. Merchant, Crunch, Feed the flames, and hotblood berserker all enable card trade ins. Unstable form, Hurlers, and Crows all provide extra trash cards, sometimes the trash even gets cast.
Berserk plus pump spells allow for some good burst damage.
Unstable Form or Permafrost are answers to big time units or units with Lifesteal (usually Vara). Combine them to deal with an SST or Tavrod.
Dusk raider + Feed the Flames is good times.
Snowballs and tempers have a surprising amount of utility.
Market - I usually grab a Permafrost to remove a blocker or Kaleb's Choice to protect against a sweeper (or kill an opposing frost). Torgar is for when I'm threat light (thinking of testing Vadius in this slot). Downpour mainly to deal with Grenadins (Crystallize though great is to costly at 5).
Haven't tested with Ixtun Merchant, as Jennev has provided good market options and the aegis is often relavent.
Sad I had to cut West Wind Herald as a fun combo with Unstable form, but needed the space for permafrost. I have a couple of Vadius, but the deck already has a lot of 3s and I didn't want to cut any for him. Sadly Fire waystones also had to go so I could run enough sigils for undepleted seats.
