I'm looking for a quick trick or two that could be done with a Rainbow Deck without revealing that it's a Rainbow Deck.

I want to avoid doing a deck switch.
I don't need anything super specific or a method explanation but what type of effects could I start with where the card backs aren't shown (or only one is shown) before I actually get to my main Rainbow Deck effect?

Check out Rainbow Deck on Nick Einhorn's At the Table Lecture. https://www.penguinmagic.com/p/S18610

Not only is that trick awesome but so are most of the effects on the download.

Will do, thanks Paul

Replace the four aces with regular bikes. Use one as a cover card on top so you can casually flash the back of the deck. Spread through the deck face up and take the aces out. You can now do Twisting the Aces, Dr. Dailey's Last Trick, etc.

Nice, that's good Frank

Joshua Jay's "Prism Deck" does just that in his performance (and teaching). Starts out as a four Ace effect flashing backs all along, then reveals the "Rainbow/Prism" deck and has effects that go from there. You can see a decent part of it in the trailer.
