Good deck. I advise mulliganing 2-mana spells against combo decks, because only they can save you from death on the 4th-5th turn. Also, a good solution would be to leave crystallogy, weapons, 1 draenei or draw. SP priests and quest dh are a bad matchup. Only God can help here. Use 2-mana spells to protect your board and set up lethal!!! Remember about clearing your opponent
