I believe I've just played the craziest round of Hearthstone battlegrounds that I'll never be able to recreate in my whole life.
First things first: I had a really bad start with Omu. That guy usually needs a token generator in the 1st round in order to completely faceroll, but I didn't get one. Luckily some guy who played N'zoth (the one who is the only character who can get the 1/1 fishes that accumulate all deathrattles that are triggered on my side of the board and trigger them again upon death) left the game in turn 1, leaving only the fish on his board.
Omu is the kind of guy that can upgrade the tavern much quicker and thus gets to pick the first Tavern tier 5 and 6 minions which was the only thing that allowed me to win.
At some point where I was on the losing end at tavern tier 5, I was able to buy 2 Murozond (which gives you a random minion of my last opponent's warband right into my hand when he is played) and saw that I was about to play against the dead player mentioned above. So I quickly bought them, played against him, played the 2 Murozond, got the 2 fishes and in the same round trippled some random card on my board which gave me the snake. The snake summons 2 random deathrattle minions upon death.
That means the snake died --> Summoned 2 random deathrattle minions --> The fishes copied the deathrattle of ALL 3 of them, and upon death triggered those effects again. I basically summoned 3 times 2 random deathrattle minions, which is already extremely strong to begin with. That kept me alive during midgame.
Then I instantly upgraded to tavern tier 6 and got a wolf. That wolf upon death gives all beasts +5/+5. The snake and the fishes are both beasts. Then I trippled the wolf, which means upon death he gives +10/+10 to all beasts, but I also got to choose a minion of the tavern tier 6. That was luckily a snake, which I was able to triple because of that as I already had 2 snakes. Now those snakes summoned 4 minions upon death.
So that means --> All beasts get +30/+30 and I summon up to 12 deathrattle minions. That's absolutely insane. But that's not enough. The Baron (the 2/14 guy) triggers all deathrattles 3 times (because he is already trippled).
Summed up: All beasts get +90/+90. You can never have more than 7 minions on your board anyway, so the strength was shifting towards the wolf buff.
It was absolutely insane! the best minion that was summoned by the snake was a Fiendish servant. That guy has a deathrattle that gives a random minion the attack of the minon triggering it. So when the 1st fish died, he gave 1 random minion +30 or so attack. The 2nd fish gave 2 random minons +60 attack. The enemy had absolutely no chance to do anything against that even with a murloc comp with a trippled bran, where every murloc had 80 defense.
A trippled tripple snake. And a trippled tripple wolf buff. Absolutely crazy game. I have never seen something like that.
Oh and the hydra attacks 3 minons at once and the spider is poisonous, killing any enemy it deals damage to. Both are beasts of course.
