I thought it had a good chance at 12 wins, based on previous 12 win mage runs. I figured for sure it would go 8-10 wins at least.
However, the RNG gods felt otherwise.
0-1
https://hsreplay.net/replay/h7bjW2sBhv3EbmGic5PRrYA combination of an incredible early game and topdecks, followed by my missing several key drops starting at turn 4, as well as prince malchezaar giving him very solid legendaries, made this a very difficult match. Even the mad bomber went 3x to my face, followed by a topdecked firelands portal for lethal. Looking at the replay, other than probably wasting my ice lance, I don't think I did anything wrong (if you spot a mistake, please tell me)
0-2
https://hsreplay.net/replay/E44RvEg8sVn2P7qH9H37L8Okay, well, starting 0-1 usually means the next game is a free win. Right? Well, not when you're facing... dragon rogue? And don't get any early drops again? Another truly awful draw.
1-2
https://hsreplay.net/replay/ik37Z4YxrvpMR4tkZ5xt9JThis guy had a pretty good start as well, whereas mine was weak, like the other games so far. However, he stalled out in the midgame, whereas I managed to catch up and overwhelm him. Instead of flooding the board for maximum damage, I kept back several minions, in case of some insane AoE plays, which he ended up having. I figured since he wasn't doing much he had to have something like that in hand.
1-3
https://hsreplay.net/replay/ZQDqFrPPfF2gnwY3zyi2uTI'm not entirely sure how a constructed midrange shaman made it into the arena, or why it was only at a 1-2 record, but there you go.
This was quite possibly the worst run of RNG I have ever seen in matchmaking and draws. Several of my 1-3 mana cards were drawn zero times in all 4 games. Again, if you spot any mistakes in play, let me know, but other than the ice lance in game 1 and playing the piloted sky golem when I did in game 4, I didn't think any of the plays were wrong.
