A strong and unexpected weapon for the last days of the current meta

Last month I won 19 games in a row with this deck between ranks 7/3.
The question now is how to tweak it after Creeper’s nerf ?

Druid has decent 6 mana spells, and is better than Priest in the early game

There are 4 cards requiring a spell and thus a high probability that some of them become dead !?
I’ve played the deck without archivist and with a third spell and an extra taunt, with decent results.
