Hearthpwn

I had been prepping for awhile and this dude (at 6 health) plays a yogg to steal my yogg then dupes his yogg with a killing board next turn. But, the turn before I prepped getting secret that summons a 3 cost card when he ends his turn with no mana and also got a concoction that does 3 dmg some turn before. After his turn (which he had ended with no mana) I got a 3/5 card which I promptly hit face with and used my concoction. TLDR, nice yoggs bro it'd be a shame if I didn't care and killed him anyways.
