Well, I was almost sorry for the mage I fought with my mage... almost. He had a really good draw (or a better deck than most). The early rounds were me dealing with his perfect counters. He managed to keep a Mana Wyrm and a Flesheating Ghoul out which I was struggling to clear (he put up 2 Ironfur Grizzly's and the mirror image spell). I eventually got through all of them, needing to use Loetheb, and a Piloted Shredder (and a mirror image to protect the Shredder), and he finally cleared my board instead of continuing to go to my face.
At this point I took control. The Shredder spawned a loot hoarder. I had played my ice block secret earlier, and I pulled out a mad scientist. He used his hero power on the hoarder, puts down a sorcerer's apprentice, played a secret, and then played a blood knight. I play a explosive sheep, which triggers his secret (a mirror entity, so he gets an explosive sheep as well), at which point I say, "sorry", attack his hero with the mad scientist, use my hero power to kill my sheep, which blows up (killing my mad scientist, which pulls a duplicate secret for me), kills his apprentice and explosive sheep, which blows up, and finishes the board wipe killing his blood knight. I then played a Ethereal Archivist.
This is where it gets bad.
He fireballs the Archivist which triggers my duplicate (so I get 2 more), and plays a water elemental. I play another archivist and another duplicate secret. He smacks the archivist with his elemental and then plays a mirror image. I play another archivist, and then use the echo of medivsh spell, to get 2 more archivists. He flamestrikes (killing an archivist, triggering my duplicate, giving me 2 more archivists), and uses his water elemental to freeze the second one (his elemental dying on this). I play 2 more archivists (giving me 3 on the table, 2 are 5/5, the third 7/4). He finally quits. It was a good thing I guess, cause I was going to play another archivist and another echo the next turn.... Only counter at that point would have been a deathwing.
