Eredin doesn't even really play like control. Nothing does. Those officers can routinely be 20+ point bronze units.
Well, I've been having some success with this list (admittedly in casual mode only):
Eredin
2x Wild Hunt Warrior
2x Wild Hunt Longship
3x Wild Hunt Hound
3x Biting Frost
3x Drowner
2x Wild Hunt Navigator
1x White Frost
1x Abaya
1x Ifrit
1x Nithral
1x Scorch
1x Frightener
1x Caranthir
1x Geralt: Aard
1x Imlerith
1x Drought
The deck exploits the fact that most decks don't seem to be running weather clear anymore. For example Dethmold used to be core in every NR deck and now it isn't, same goes for Water Hag / Abaya in monsters. The deck can put out a total of nine rows of weather, and has Drowners + Aard + Frightener to force opponents to keep taking damage. The control is strong enough that one game against a NR player I actually ended a 5-card round 3 with him having literally zero power (he did walk into a 22-point Scorch though). One thing I like about the deck is that I can mulligan freely. The only card I really don't want in my hand is Biting Frost.
The Scoietal decks are bad matchups but I'd be surprised if any deck has a good matchup against them. It's still possible to win vs. mulligan if they commit too many Officers in a single round that I can pass on. I won my last game for example after baiting a pass with Frightener in round 1, passing after going ~30 points down in round 2 vs. two Officers, and then using Drowner and Aard to attrition through his 2x row weather clear in round 3. He probably believed that round 2 was going to go for longer after I coated his board with White Frost, hence the Officers play. Spelltel is very hard. It feels like the best way to beat that is to lose the coin flip, then play Frightener. That gives them nothing on my board to attack, invalidating a large swathe of their cards. If they play on, I pass. If they don't, I win the round, then start by playing silver / gold weather in round 2, again giving them nothing to attack. Playing Wild Hunt Hound is also OK - as a 3-power body I'm happy if they use an Alzur's Thunder on it.
One possible problem is that mulligans can actually be quite hard since all the individual cards are so good. I tend to mulligan duplicates of every bronze Wild Hunt unit (reasoning that Navigator can pull out more), along with Biting Frost of course. If you play this remember that Imlerith and WH Warrior do not deal maximum damage with Drought - save those for frost rounds. The deck also likes long rounds since it's got weather, so if I win round 1 I tend to pass round 2 without playing.
Cards I'm thinking of: Jotun for obvious reasons, and Earth Elemental (probably over the Longships) since there're quite a few turns where I'm just continuing the round and counting the weather ticks. The Longships seem like the weakest bronze cards. They could generate 11-13 power, but so can the WH Warriors and Drowners. Eredin bringing out a Rider is also 13 power, potentially more if frost is on the board.
