On two accounts, I experimented a little because I had a ton of Arena passes to burn.
No deck will always get 6 wins, but my most consistent deck has been this DK Handpump, which is good for at least 3 wins on average. And, I got my first 6-2 victory tonight with it.
Beware of DH (too fast) and Shaman (kill before the cast when drawn cards start hitting).

It feels like the rotation-proof shell here is to run your highest-cost cards and cheap removal.
You’re probably running a lot of Legendaries, so Highlander is also not a bad assumption.
I’m not sure what I’m running beyond that, though.

Not sure if this is what you’re running this time, but it’s still a good option for an early-game win.

I cut one Creation Protocol for a second Animate Dead.
CP becomes a dead card if both Astral Automatons make it to your hand before it gets played.
You have to make sure CP is in your opening hand and at least one AA isn’t, with a live draw before you can play it at face value, 2 if you forge it for the extra copy.
It feels great when it works, but not so much when it doesn’t.

No clue how well this works.
My first opponent saw a Preist and conceded turn 1.
Got my pack, maybe play for fun later.

Rotation killed a lot of the cards listed here back in November.
Astral Automaton and Storm Giant decks are probably still viable, though.

I don’t remember, but then I didn’t keep the decklist either.
I’m guessing it’s whatever Tempostorm had featured that week since I don’t play Standard much.

Yep. Still solid in 2024. Get those patrons!
I don’t know which two cards would not load for me from your list.
I expanded mine with Prince Renathal for the padded life total and more survive & take damage triggers. And, I swapped Oasis Thrasher for Whirling Combatant, for more triggers.

Notable exception:
Replicatinator-inator if you’re still stuck on the envent quest.
I hope I get one here.

Watch out for Soularium + Soul Barrage

I’d go so far as to suggest Shard is your MVP here.
It shuts down all swarm decks, and is card draw when you’re the swarm player.

My opponent (Mage) managed to get Thunderbringer down on turn 1.
I only saw it and the coin played. What did I miss?

Too slow against token decks, even operating on plan.

I didn’t play it, but Silverhand Pally is a solid aggro choice.

My opponent in the Unholy test was running a hybrid of all three runes.
I’m not sure what else they had, but if I had them on this account I might have included Amateur Pupperteer or Down with the Ship.

For Blood, I’m thinking corpse generation into Corpse Explosion to clear the way to begin beating face with Corrupted Ashbringer and Gnome Muncher. (Pretty much how the original pre-con Blood deck worked.) I’m sure there’s an aggro version that could be built here too, but I’ve never been a fan of Blood.

Frost worked great against the Face Hunter I tested against; conceded when he realized I had nothing but answers for his board.

This is where I admit my choices for Unholy might not be the best since I usually run it as a 40 card, so decisions had to be made. Power loss due to Grave Strength not being available is why the Necrotic Mortician is in, as an extra Nerubian Visier, to maybe cheat a GS in.

The answer was, that Corpse Bride was fine since there is no corpse sink in that deck other than Malignant Horror, and Asphixiate should have been in there.

Frost is tough without Frostwyrm’s Fury, but this seems like an okay control deck.

Oh right… That’s why I’ve got no dust. I was replacing my common and rare DK cards.

Here is the starter, runeless, shell I’m building with. Swap in whichever rune cards you prefer.

Corpse Bride, I’ve always felt was hot poop, probably the first card to go (might be a good slot to play with Arthas’ Gift, if I want to be whacky and stay runeless).

Any time Epics/Legendaries are out, Bonemare tends to become a MVP in the late game.

This time around will be interesting…
Like many other players who missed what was going on at the time, when Core Set became a thing I scratched my head as to why I suddenly had two of everything and ended up dusting all my collected copies.
The recent rotation moved a ton of staples that had been around from the beginning (and most of the original DK cards) over to Legendary.
I run two accounts, one competitive, the other just for Tavern Brawl & Twist. Go figure, the latter is presently dustless. I guess I’ll try some Core Decks and see what I can swap in to make them work.

*newer players
Kind of need to have at least been around for Galakrond.

I definitely, agree on the approachable front. There are still a few cards that new players might need to craft, but it’s not “buy a bunch of packs and good luck” level anymore. As much as I like being able to use my old cards from way back, and with it some of my favorite decks from over the years, it was a solved meta. No room for innovation.
