It's an interesting question and ultimately flawed, asking what I would do is is the same as asking what clothes I wear.
I am not sure why everyone is suggesting organic magic you have your cards out you may as well use them. short of knowing your skill level and repertoire not to mention your character and personality. I guess slop shuffle triumph is one of the best effects you can do, also look into back in time by jay sankey as it is one of the best takes on the plot. (not to mention it takes the presentation away from so this drink guy did this.)
most card effects follow a fairly linear path pick a card, lose it, find it. And it only it shows you can control a single card, triumph routines demonstrate control over the entire deck.
