Hearthpwn

I had a 9/2 northsea kraken and some other creatures. He had an archmage. I knew that he would trade the archmage, but no. He topdecks unstable portal, unstable portals into justicar trueheart, then pings my north sea for 2. I lost the game in fatigue because he had that 2 damage fireblast. Never lucky. In the late game, i draw a yeti and i think i might have a chance, but no, topdeck bomb lobber.

Pretty unlucky, I can top it though...(It happened to an opponents of mine).

He played Leeroy Jenkins as a finsher (ihad 5 health), I have Knife Juggler on the board; Two knifes straight to Leeroy.. Good game indeed sir. 

I had 13 health, as a roogue. HAd prince gally wix out against a hunter. He had no beasts. The coins enabled him to win with double kill command, quick shot draw a card, play coins drop the archer and then use hero power and inspire for a total of 3+3+3+2+2 for 13 total. Gallywix killed me.

Shaman plays Earth Elemental to block my small minions, but I have fireball+ping for 7 damage lethal next turn.  And then he runs his piloted shredder into my piloted shredder. He gets a Vitality Totem to get out of lethal range and wins the game.

This was more unlucky for my opponent than for me, but I once built a joke Hunter made of only bad cards, and I managed to pull off the most absurd win by becoming Ragnaros on turn 4. It went something like:

Turn 1: Shieldbearer + double Wisp

Turn 2: Coin Alarm-o-bot

Turn 3: Summon Majordomo Executus with Alarm-o-bot

Turn 4: Feign Death to become Ragnaros and snipe opponent's Deathlord with hero power

I don't think I'll ever have a better game for the rest of my life. 

That is unluckiest ever? I don't think so. Bad rolls are quite common.

It could be worse.

You could draw and play Troggzor the Earthinator turn 5 in Too Many Portals! Tavern Brawl and go on to lose the game.

Just ask my opponent that I just faced :D (Polymorph ftw!)

i remember the first arena i have done, i was 11-2 so far, one more win and i m good, i open with malygos, flamestrike, and barongeddon, so i mull into flamestrike malygos, pyroblast.  those were the only cards i have cost more than 6.

Oh yeah?  One time I top-decked Cenarius against a Mage and buffed up four 4 health minions to 6 health to prevent a good Flamestrike from happening.  Then he topdecks a Flame Leviathan to nullify my Cenarius and then gets off an insane Flamestrike anyways.

I was watching a championship final, and guy A was winning, when guy B played Mal'Ganis, A got a lot of damage from imps, and used his removal on Mal'Ganis. On the next turn B used Bane of Doom and got another Mal'Ganis from it. He lost 3-0 that day over pure bad luck, and recieved 500R$ (Arround 120 dollars at the time) less than the first place.

Well this just happened...I had a mage sitting a 2 health and I was certain to kill him on the next turn.  Then, my Piloted Shredder pooped out a Wrathguard.  His last two cards were Flame Lance on my Wrathguard and a Fireball to my face.

My opponent had theunluckiest moment. Summon sneeds then revived it and stuff gets kel thuzad then i trade my sylvanas into sneeds get kt then he kills his sneeds gets rag hits face and im at 1 hp. Then i trade syl again get rag then it hits face for lethal.
