Not only are Flourishes and Revalations difficult to perform, they are worth learning to help your presentation more appealing to spectators. I find it much easier to perform double lifts by :
First-having the spectator choose a card but not look at it and place it on the deck.

Second-by doing this you can do a double lift showing them one card as two. This way you place both cards back on top of the deck leaving an indiferent card on top.

Third- this gets you ready for an Ambitious Card routine.

any other ideas...

I suggest purchasing the David Regal series as well as the Michael Ammar VHS voulume's to learn easy flourishes.

I'm currently using the same way to force cards-fanning the cards, letting the spec chose any random card, put it on the top and double lift. You can also practice the classic force while your doing this force(when they pick a random card).
