Some rough matches today, I dropped down to 17, bounced back up to 15, but then finished at 17 again. I may play some more later but I don't know. I took out some of the spell cards designed just to stall, like Mirror Image and Frost Nova, and added some more 3-damage, 2-mana cards that can trade into some 3 mana cards, especially mechs, to help maintain the board in the early game. Since I'm using pretty basic cards I think my game needs to play more control than to try to out-damage my opponent. I'm confident this deck can get up to rank 13 or even 12.
This happened, which is why fuck mechs, fuck mages, and fuck everything.
But I won this close match, it was against a hunter so he only needed 1 more turn to hero power.
Then I had this close match also. Bad screenshot but my opponent had lethal and then I top-decked a fireball.
