Careless Whisper (Auralian Wisp Recursion) v1.4

This is my favorite deck to play at the moment. Heavily inspired by "Arcanum Wisps", which you can see here. Wouldn't go so far as to say it's Tier, but it's pretty solid and my goodness is it fun when it goes off smoothly.

I found the curve was a little top-heavy and reliant on cards like Dread and Sadistic Ritualist that just don't work fast enough to get you the game back when you're on the back foot, so instead refocused on cycling the little guys until they become not-so-little guys.

Pathlighter and Nocturnal Creeper with Xenan Initiation are your removal (as well as Weary Spiteling to a lesser extent). Don't be afraid to kamikaze them into enemies early in the game, since you'll be getting them back later. There's nothing more satisfying than a Killer Pathlighter getting the Tribute bonus off of its own death 2-3 times in a turn while it gleefully wipes out a good chunk of your opponent's board.

That being said, do NOT sacrifice/kill off your own units too readily unless you have a Dark Return, Soulbringer, or Shadowlands Guide in your hand. Memory Dredger is great once you've established your board, but gives your opponent too much time to counter to be a card that can hold up the deck single-handedly. It's for that reason that I dropped Dredger to 3, rather than 4 copies.

Secret Passage pulls double duty, both helping you get your wisps into the grave -and- letting cards like Dredger deal with chunky blockers with the one-turn free Unblockable you get upon summoning it. It's also a potential win-con in the late game if you happen to accumulate a chonky Weary, Pathlighter, Creeper, or anything else.

Praxis Arcanum fits into the deck in essentially the same way that it does in the aforementioned Arcanum Wisps. It makes your already cheap stuff cheaper (or even free, in the case of Weary/Pathlighter), making it so that late game, your Dredger can fetch your Void Drummer, and your Guide is grabbing Creeper, Dark Wisp, as well as your Killer one-drops. Enjoy your late game, zero-cost 12/12 Flying Killer Unblockable Weary Spiteling!

Arcanum also helps mitigate the speed problem with Memory Dredger and Void Drummer than we mentioned before by giving them Charge before they hit your board, possibly netting you a surprise resurrection/buff of one of your lil' beatsticks. It happens to combo especially well if you happen to get Azindel, Revealed onto the board from your market. It's pretty dang fun to be playing 3-4 of your opponent's cards per turn at a discount of 3 because of your Unblockable Helici, Drummer, and whatever else you've managed to buff with Secret Passage.

The Market
The Market choices are to deal with big potential threats. Banish is there for quick removal if you didn't net a Killer Deadly wisp early, Decay is there for the Adjudicator's Gavel or other grave-hate attachments like Vanquisher's Blade. Sandstorm Titan helps you stabilize if you get swarmed by flyers early. We've already talked about Azindel, but he synergizes well with Pathlighter's Infiltrate effect, and the fact you can use Guide and Soulbringer to grab his Helici back if they get removed makes him a useful edition. He's saved my butt more than once.

If there's a flex slot here, it's Vara's Choice. I placed it here because I don't really have any reliable Silencing effects otherwise, and the Silence/bounce effect can help shut down a singular nasty threat. Open to suggestions for better options, though!

EDITS:
- Dropped Secret Passage and Praxis Arcanum to two.
- Replaced dropped copies for 2 Predator's Instinct to add consistency to the ability to give units Killer. It also helps to smooth out the curve.
- Replaced Auralian w/ Kerendon Merchant, for a couple reasons.
-- Gives me another Deadly unit I can drop Killer onto. If I have Arcanum out, I can even fetch it with Dredger!
-- Shadow has more tools from the Market that fit our deck strategy than Time does. Specifically getting Vara, Vengeance Seeker and Grasping at Shadows helps us stabilize at midrange against fatty threats in the case of the former, and fetch some quick resurrection in the case of the latter.
- Dipped Primal at the advice of another user to get access to Haunting Scream.
- Dropped the Praxis Arcanum for two Dread. Haunting Scream makes them much more usable, and more often when I'm on the defensive, I need a charging Lifesteal unit than I need a site that I have to defend.

v1.4 Edits
- Lil Vara is too good with recursion to not include in the main deck, and adding 2 more Banish helps deal with Adjudicator's Gavel mainly, as well as removal when I don't have a Deadly Killer on hand.
- Drummer is better with Scream, but has become circumstantial a lot of the time, so I've dropped it to two. Same goes for Secret Passage.
- I dislike the uncertainty that comes with giving opponents' card adv with Twilight Hunt, but caved to using it because of the extra card + chip damage in a deck without a ton of Extra Draw options besides Creeper.
