I personally change my farming/boss decks a lot depending on the minions/boss I am facing, and one of the most annoying things I have to face is individually clicking on each spell to remove them from my deck. I think an implementation of a "button" in your deck to clear all spells would be very handy for anyone who needs to change their deck for whatever reason. It would cut down time and the strenuous task of clicking each individual spell.
An example that i might use this spell is if:
I have to change farming deck for balance minions (I am balance)
