Race to death: Winner is the one who dies first. Warlock would been banned. It would be neat to see that race where players are trying to heal one another and alex themselves to get low quickly. Idea is cool.

Weird challenge. I think leave Warlock in place, there would be a challenge to outrun him in self-damaging. I think a priest could turn 7 Velen, then while the warlock would be unable to face against him, Auchenai then double Antique Healbot for 32 damage to self. IMHO summoning minions here would be detrimental unless hastening one's own win. But, I'd like to see how others would play this. Poor Hunters with their selfish power. :D

"LET THE LEGENDS FIGHT" 

Each player has to include 26 legendaries in his deck or as many legendary as possible  

I think there are some good reasons to play that. First of all, everyone likes to play with legendaries ;) . But the main reason is that we would see a Hugh variance of decks even though it includes deck construction. I like the tawern brawls where you must construct a deck, because you have to think about the theme of the tavern brawl and create a deck with lots of synergies with the theme. The problem is that after one day everyone is playing the same. You have 2-3 common decks. The only way to avoid that, but still having a brawl with deck construction is to abuse the variance in the collection and the most variance is with the legendaries. It won't be fair for all players, but it wouldn't matter that much, because of the high variance of deck types. And the players who would have an advantage are those with just a few legendaries, while older players have a disadvantage.  Therefore it would be fair in a certain way. I really like the idea of this brawl, also it would have an individual touch.

Mana Curve

At the end of each player's turn, that player takes damage equal to his unspent mana crystals (preset decks for each class)

That should be named "Mana burn" instead. (Thanks MTG) One would need intense draw to not take a lot of damage. I like this idea.

Everyone's Invited:  Choose three cards from each class and three neutral cards.

Every minion with text is silenced and given random text from another card in the game before entering play but after you play it. 

You could play a Wisp that miraculously clears your board and discards your hand or gains taunt and divine shield. Your Anub'arak could deal 4 damage to itself. Your Flamewaker could give adjacent minions +1 spell damage. 

I am a big fan of the random brawls where you don't have to create a deck or if you do, you won't control most of the elements in the deck.

Blackheart's Party

Build a deck of 30 cards, and either the starting hands are all full of doubloons (coins), or a coin is given at the end of each turn. And all pirates cost 1 mana.

My Deck is My Temple

As the guardian of your very own Luxorian temple, your Hero power activates automatically at the end of the turn. Costs 0 mana, too.

"LET THE LEGENDS FIGHT" 

Each player has to include 26 legendaries in his deck or as many legendary as possible 

The problem is that not all players has 26 legendaries to fit in.  Not many actually.  The entry barrier to tavern brawl is to have a hero at level 20; You should be able to play "constructed" tavern brawl with only your basic cards.  As many legendaries as possible will be wildly unbalanced depending on what legendaries you have, and how much.  But it's simple to fix the idea here:

Let the legends fight (by DynamischerDiskord)

Pick a hero.  Fight with a deck made of 6 random spells from that hero's class and of 24 random legendaries.

No, please not. Then we have a RNG based and those usually have so less synergies. My idea is an attempt to break out of the either constructed and everyone is net decking or RNG based without synergies brawls. And it would include a personal touch. It would be unbalanced since people with just a few legendaries could build standard decks and just include the few legendaries and they have an advantage in comparison to older players with lots of legendaries. However, the variety of decks is Hugh and you don't play always against "bad match ups". Of course with certain decks you don't have the chance to have a really high winrate. But that is not the point from the brawl. I just like the idea that everyone picks his own legendaries, where he is proud of, and built a deck around them. And then you compare your own personal deck with others. That older players have a disadvantage is something I consider as challenging for them and I personally wouldn't mind if I lose against someone with just a few legendaries, since I grant them there success. So even though it is unbalanced I think it is worth a try and it would be a nice change to the other brawls.

 Or:
Boss Fight
We could play with any of the normal- Bosses of Nax and BRM against each other. Some decks may be quite unbalanced but it would be something new.

I'd like to see a TGT themed Tavern, with preset decks of th enew cards, or constructed decks with the improved Hero Powers.

The hero powers would be awesome.

I would like to see a legendary battle.

Legendaries only and you can add any amount of each legendary to the deck.

And another idea would be,

You opponent cards are visible!

Transcendence Brawl (Based on tutorial spell): Your hero is immune while you have minions.

5. War of Horses 

All players have bundled 20 Dreadsteeds and 10 Whirlwinds.                                                                                                                                                                                            

Sadly, this one is stupid. Whirlwind does nothing to a Dreadsteed, except preventing your steeds to go face if they are able to, so whoever has hero power to do damage to face wins *cough*Hunter*cough*.

The next Brawl we gonna see is for sure arround TgT to promote it one week before it releases on the 24. just like they did it with GvG Arena.

Maybe we´re lucky and they set some special prices like 5 TgT Booster if you get 50 wins.

Miracoli rogue decks

Both players play with miracle rogue decks pre leeroy jenkins and gadgetzan nerf.

How about you play with your opponent's deck, you could both play eachother's crap decks. 

A great idea from me, you craft a Deck and before the Match begins, both Players swap the Deck with the Enemy, so it means you literally want to create the most ugly Deck ever seen, probably just wisps and magma Ragers, but another idea would be insanely high amounts of Mana cost stuff. Only spells?! Very funny and beginner friendly.

Btw. i rly would love to see a Hardcore Brawl/Mode.

The idea is, you see no numbers on cards/heroes, i got this a few times cause of a bug in the arena and co.

Sure this isn´t very Beginner-friendly, but pretty funny and you simply have to think and learn to remember harder while doing your Stuff.

All hero powers are free
or
All hero powers are upgraded

Another one, All Minions have the Ragnaros Ability and the dmg would be similiar to the Minions attack.

I'm sure it's been said many times, but a Nozdormu mode where your turn only lasts 15 seconds and you get to make your own deck. This could be quite fun and/or frustrating.
