that deck I posted yesterday is doing exceptionally well on ladder. Mechwarper is indeed ridiculous and I'd be surprised if a nerf doesn't come soon (reduced-cost mechs are OP).
I finally got to go against handlock today and admittedly got extremely lucky but was able to overcome double taunted giants (twice) and Jaraxxus. Likewise, control priest was a long game but I survived double Holy Nova, a (Thoughtstolen) Consecrate and other Anduin antics because Jeeves lets you replace your board.
I saw a good deal of deathrattle hunter and Classic/Naxx-era zoolock today as well, beating them too (though most of them were very close games). There's no doubt about it, mechs are the new cancer of Hearthstone... deal with it.
