I almost can't believe I beat a secret mage who got to play 5 loathebs, with 3 of those being back to back almost.
The only thing I had going for me was that I was almost full hp, he was down to 2-3 cards, I had a healthy hand, and I could deal with loatheb the next turn fairly well.
Then he played 2 more secrets.
They turned out to be mirror entity, duplicate, and counter spell.
I planned on playing azure drake, rockbiter on my haunted creeper to remove the azure drake, and lava burst on loatheb.
I triggered the counter spell first with rockbiter. Then followed up with lava burst to remove the dude because I was still assuming that at least one of those secrets was mirror entity. Because I already had 2 totems on board, 50/50 chance to get taunt totem. Success. But yeah, duplicate triggered on loatheb... so loatheb hits the board again... I play an 8 mana feral spirit, and he hits loatheb again. Totem pass. No cheap minions to bait out mirror entity and no way to use lightning storm to clear either. He also played another secret AND pinged his undertaker to deathtaker indicating it is definitely duplicate.
With 2x 5/3s on board, due to removing feral spirits each, I finally got a chance to cast a spell.... azure drake (trigger mirror entity), lightning storm = board clear. Of course he got another 2 loathebs in his hand, but not much else. He did play a flamestrike later on but I already had him down to 3 hp with doomhammer in hand.
