There is no dust refund but if you have unlocked the golden copies of Mind blast and Vanish while leveling up, now you can disenchant them in the Hall of Fame section of your collection. As they are considered Common cards now, for 2x golden copies of each you will get 200 dust.

Exactely! Worked for me perfectly as well. You can easily build some pretty consistent Dragon and Rush synergies with only RR cards. Dragon roar works very well in this Brawl. Blew away three C’thun Priests in a row in now time.

I feel we no longer have Meta… Now we have Mecha! I even consider running some E.M.P. Operatives in my decks.
“I said this looks like a job for me
So everybody just follow me
‘Cause we need a little E.M.P.
‘Cause it feels so mechy without me…”
Her flavor text says it all 🙂

I am surprised Potion Vendor is not on the list… I feel it would be better than the Peasant?

I think It’s a perfect combo 🙂 Oblivitron for 6 Mana + 2x Arcane Shot for 2 Mana to kill the Oblivitron + Goblin Prank for 2 Mana on Mecha’thun to kill it in the end of turn. You trigger the Mecha’thun deathrattle effect twice in a turn… the second one is the deadly one 🙂
