Thanks for comment, bro.
I added just 1 devour mind because of this negative points that you indicated.
You are rigth, its very inconsistent yet. RNG can be very unfavorable sometimes. The most of decks in the ladder have sinergie cards making the things hard. There is no one settled win condition to turn the matchs more exciting =)
But realize too, this deck can be very good against control matchups, stealing DK's and control cards. I think remove Gluttonous Ooze is a little risked in this meta full of weapons. Maybe remove 1x Psionic Probe and add Holy Water be useful.
I dont know about remove Baku the Mooneater... I like the idea of improvement heal to survive and take more resources of my opponent.
One more time, thanks for the advices and have fun if you try out =)
