Here's an idea: What about Reverent Mantra?

Granted the deck does not play a
ton of white cards but you should still be able to pitch something for the alternate casting cost to save your crew from a board sweeper like Firespout. Depending on build, you could have Qasali Pridemage, Wooly Thoctar, Path to Exile, Figure of Destiny, Knight of the Reliquary, or Lightning Helix.
Certainly seems a couple Sideboard copies of Mantra would be better than a schwag fifteen-card "switch" into bad combo.
