Eh, you could argue that a board refill card (like Stand Against Darkness) or board protection card (like Steward) could be substituted with a reverse tempo card to delay a board clear (like Rebuke).  Depends on a few factors, particularly how quickly damage can be pumped out or whether such a board can be buffed to keep it safe from the impending clear.  But they do fill overlapping purposes. 

Of course, Godfrey and Duskbreaker don't care about being Rebuked.

Tog + This is 10 mana and just makes the deck switch card cost 10 mana...

Yes, but less so now than before though.

Warlock and Priest both have very strong *minion* based clears.  Warrior has an okay Weapon and Hero Power based clear.

Mossy Horror probably won't be a thing, but worth at least mentioning.

Kingsbane doesn't just slot into a deck.

It requires a *ton* of support cards to both ensure you draw it and to buff it.  This simply isn't a Kingsbane deck.  Nor is it a 
"mill" deck in the normal sense.  Milling is sometimes an excellent option, but you're rarely going to try to win on Fatigue.  Mostly the Coldlights act as a flexible draw engine when combined with the Shadowstep, Valeera DK, Zola, and Elven Bard.  Those same synergies can be differently prioritized across multiple threats as well though to combine with a board full of striders and/or Arcane Giants.

This is also part of what makes the deck so decision heavy.  Choosing how to spend those bounce resources and use the draw engine.
