Hearthpwn

I like the idea to include mind blast. I bet it has some crazy moments when you pull them with shadow visions! I might have to try this deck! Might swap -1 Blazecaller for +1 Elise though!

I don't really understand the deck. What's the point of Crystalline Elemental in a OTK priest deck? Is it just to trigger the Blazecallers? There are very few recipients for Divine Spirit, just the Lightspawns and the one Tar Creeper, maybe Lyra herself and the Blazecallers as well. But you say you have lethal on turn 5 or 6 so I guess you play the combo on the Lightspawns or the Tar Creeper. What do you do if they get removed, how do you get back into the game? What do you do if you face many taunts? You've got no Black Knight, Silence or other cards to remove taunts. How does Mana Geode combine with the rest and help with OTK?

It feels like OTK is an alternate win condition. I agree though that Fire Fly might be better than Crystallines in this deck.

Can you write a guide with mulligan, match-ups and tips?

Did u play it in Ranked(rank?). What about Prophet Velen or Servent of Kalimos in this deck?

Fun deck! I think some spell damage worked in somewhere for even crazier mind blast shinnanigans would be great, I might cut a lightspawn for thalnos  but nice work. It's working out great as is thus far
