Not sure if the polkelt combo is too unreliable, maybe the card slots could be swapped for draw.

The combo with Beardo is:

Auctionmaster Beardo -> Hero power -> Tour Guide -> 0 cost spell -> Hero power -> Tour guide -> 0 cost spell -> Hero power -> 1 cost spell -> Hero power.

OR

Tour guide the turn before, and then two of the spells can be 1-cost spells.

The combo with polkelt is:

Polkelt -> Holy wrath guaranteed to draw Shirvallah.
