I like those cooperative brawls.
I got a competent partner and solved it at the first attempt.

I also remember mechazod. It was more challenging, but also quite some fun

some thoughts after playing evolve shaman with about 75% win rate:
(the deck is fun, but you lose against control decks (priest, warrrior) and druid with global buffs is too fast for you)

shaman:
T1 evolve is by far your best play.
mulligan hard for it

priest:
topsy turvy, inner fire, bless, cathedral of atonement, serenity

paladin:
showdown – prismatic beam, deputization aura

druid:
global buffs from token druid.
probably the best deck in this tavern brawl

general:
scorp-o-matic, crazed alchemist, pelican diver, recombobulator, sea giant

i don’t demand fine-tuned meta decks for random tavern brawls, but why do they keep putting those “draw a weapon” cards in a deck with zero weapons? it’s just stupid and no fun.

same goes for “draw a mech” effects in decks with zero mechs, N’Zoth with zero deathrattle minions, Frozen Mammoth with zero Fire spells.
Preparation is also a bad joke in a deck without expensive spells, in a format where your spells are cheap anyway, but the number of cards that you can play each turn are limited.
echo cards? Auctioneer? Unstable Element? The Rogue decks are a menagerie of cards that are exceptionally bad in this format

That being said, except for the Rogue deck all decks had some appeal to them.
The Hunter deck seemed to be the strong (double King Krush, Darkmoon Rabbit), but each class has more than one deck, so it’s not easy to say which class is the strongest

I aimed at Frequency Oscillator – Mistake – Parachute Brigand – Parachute Brigand – Patches.

That did not work, because i drew Patches turn 1.
Still won because i got Ysera from a portal, which is a good card at 6 mana

too random for my taste, but I never had so many hits with Murloc Holmes (third card is always the legend), and also third turn double Thaddius (first with coin, second with discount by the first) felt nice

probably a coincidence, but I got only commons and rares (zero epics, zero legends) from my 10 catch up packs in the Badlands Catch-Up Packs Mini Bundle, so I cannot really recommend buying it.

storm giant.
Honestly, the card is neutral and definitely belongs into your deck.
It has taunt and saved me in so many games in which i was behind, only to fill the board with 8/8 taunts, giving my opponent no way to punch through that wall.
It even combos with Animate Dead and Celestial Projectionist, but not with Zilliax and Irini, because it is not a mech.
Storm Giant can also be seen as backup if you fail to draw an Automaton

I tried your deck, going 10-1.
The loss came in the mirror, because he drew the mirror braker and i did not: Shard of the Naaru. That card neutralizes all opposing Automatons and also opposing magnetized mechs – mech decks were the only opposing decks that could make games close in any way. And if this was not enough, it can even be traded. What’s not to like?
(In turn, Storm Giants suffer less from opposing Shards of the Naaru, but I only had 2 mirror matches and I am not sure if the Giants would have saved me against Automatons backed with Shards.)

Bottom Line: Your deck is very good, but can be improved by cutting Ra-Den and Aman’Thul (just as you suggested), adding Storm Giant, and replacing The Light! It Burns! (which was never useful in 11 games) with Shard of the Naaru.

Yes, I think that’s the point:
I may have paid more money, but I had many months to play with those cards, while those who now benefit from the catchup packs per definition have not played serious hearthstone for a long time.

Now if they only discounted the old editions (or at least wild packs) so I can advance my collection (many cards from darkmoon and before are missing). Given the constant power creep, older editions are barely playable in wild, and in standard they are banned anyway, so it is not really justified that the old editions still cost the same as the new ones.

which 8/8 card did they copy?

thumbs up for finding that automaton strategy 🙂

honestly, without radiant elemental and sorcerer’s apprentice there is no point in this tavern brawl.

all the great options are in wild

how would this improve the deck?

i also played enrage warrior, but with zero shadow reflections.
i had location/anima/acolyte in my opening hand and was happy that none of them was a shadow reflection.

People like me, who regularly spend real money for the game could feel a little bit stupid now that others who did not spend anything get so much for free/cheap.
To buy 1000 cards, usually you have to spend like 150-200€, but those who get full benefit from catchup packs will only pay like 15% of that amount (depending on the price of catchup packs)

At least collectors get 5 cards (from different expansions they have probably almost completed) per pack, at first I thought it was a single card per pack.

in the section “villain effects” you wrote:

Work for Hagatha – “At the [XXX] of your turn, transform a random friendly minion into one that costs (1) more.”

I think there is a word missing where the [XXX] is.

you wrote:
“Update: Sword Eater was removed from Twist Wonders in a recent hotfix, because it was not supposed to be there in the first place (Mean Streets of Gadgetzan is not a part of the format).”

Apparently Gadgetzan IS part of the format, but Sword Eater is from Darkmoon, and THAT set is not part of Twist Wonders

I checked both sets, and apparently I do have 1 Blackpaw from Gadgetzan and 1 Blackpaw from Caverns.

Then I checked Thaurissan and I have 3 Thaurissan from Blackrock and 0 Thaurissan from Caverns.

This makes me believe that I could as well get a fourth Thaurissan when I buy Caverns packs, because the game thinks I do not own the card yet. How stupid is this?

The whole “Cavern version is a different card than the original version” is just a way how Blizzard deactivates the duplicate protection and should be corrected immediately.

I was careless enough to buy the “Battle Ready Deck Bundle 2” with the preconstructed Jade Shaman, C’Thun Warrior and Jade Druid decks, just because it had some legends and epics in it that I was missing.

However, I only got 1 Aya Blackpaw although it is included in 2 decks.
I still got 2 Brann and 2 Thaurissan (also included in 2 decks), so the missing Aya Blackpaw does not make sense to me.

Is the missing Aya Blackpaw a known bug?

Adding Xyrella, the Devout to the deck (cutting an Infected Peasant) improved the deck a lot. The battlecry (repeat all deathrattle effects) usually gives you multiple Korraks, and the hero power allows you to snipe enemy Korraks every other turn.
(Speaking of Korrak, I am so afraid of Korrak that I even consider adding Ruststeed Raider, Steel Rager or Faceless Corruptor to the deck. Ruststeed would leave a 5/5 after killing Korrak, because it does not lose its attack bonus before going into the void)

Since many popular removal options target randomly (Sinrunner, Sylvanas Windrunner, Convincing Infiltrator), leaving extra creatures besides a big Void Singularity goes a long way. This makes Foul Egg, Haunted Creeper, Infected Peasant, Serpent Egg, Vrykul Necrolyte and Pozzik also valuable in the later game. Voodoo Doll on the other hand is a great removal tool in this tavern brawl that can not be deflected by extra creatures. Since Haunting Nightmare does not leave an extra creature behind, it should be replaced (probably with Plagiarizer).

Many control mirrors are decided by “I win”-effects like that of Rivendare’s horsemen. Death Knight has an advantage here because of Patchwerk, and also Theotar, the Mad Duke can steal a horseman from your hand and thus keeping you from winning through this route. Xyrella, the Devout gives you a second chance here by triggering Rivendare once more. Some players also used Steamcleaner as a tech card against Rivendare.
Another “I win” effect that I encountered was the Purified Shard that you get through Priest’s Seek Guidance quest

I have lost games in the most hilarious ways, like Warrior stealing my big Void Singularity and then playing Charge on it, attacking me immediately. Once a Priest used Zerek’s Cloning Gallery to find the 3 Horsemen from Rivendare Warrider immediately

Priest seems to be the most popular and probably also the best hero for this tavern brawl.
The deck utilizes the aspects of this Brawl quite well: many creatures die and most of the time the opponent has exactly one big minion.
deathrattle minions that you want to trigger immediately (Foul Egg, Serpent Egg, Infected Peasant, Haunting Nightmare, Pozzik, Vrykul Necrolyte’s target) cover the early game.
Korrak the Bloodrager (mvp), Magatha (no spells!) and Famished Fool generate value in the midgame.
Big Game Hunter, Sinrunner, Convincing Infiltrator, Najak Hexxen and both types of Sylvanas snipe the enemy’s Void Singularity.
Rivendare, Warrider was an attempt to have outs against the most defensive opponents like Blood Death Knight, but there are probably better options
Mind Eater was given the nod over Dead Ringer, but I think they are equally good
Haunting Nightmare could theoratically be replaced by any 3-drop that has a decent deathrattle like Shadowed Spirit, Student of the Stars, or by Plagiarizer)

There are also some minions with high stats and drawbacks that are negated by the void transformation (Humungous Razorleaf, Imposing Anubisath, Incorporeal Corporal) that were also popular, but I rather included minions that left me with extra creatures during my opponent’s turn to make it more difficult for Sylvanas Windrunner and Sinrunner to Hit my Void Singularity

i hope there will be preconstructed decks again.
i like to buy legends for gold, and i am still missing a lot of them from the early days

given the limited usability (you can play standard cards in wild, but you cannot play wild cards in standard) and the general lower power level (due to power creep) of wild cards, i wonder why they do not throw in more extra packs or maybe an extra legend
