The key to corporate gigs is to perform WITH the audience and not AT the audience. All of your tricks do that but every one of them only engage one person at a time. Clutch is not something that I would use as a closer.
I recommend picking up Mark Wilson's Complete Course in Magic. Funnily enough, you will find Clutch in it but more importantly you'll also find tricks of different styles that involve a handful of people at once.
There's a nice Three Way Test, a half gag/half trick Ping Pong Ball lottery prediction type effect, multiple rope routines that can use the entire audience in some way, a handful of Do As I Do effects, envelope work, etc. In fact, in addition to the Three Way Test being a great effect on it's own, it's also an opportunity to introduce the other objects that you will go on to perform other tricks with.
Generally speaking, cards should be avoided in this setting due to their small size. There are exceptions, of course. Usually the exceptions have one thing in common- the cards are nothing more than a smaller prop for a bigger effect. An afterthought, not the focal point. An exception is Tossed Out Deck which works well with bigger groups. Any effects that predict what card will be forced, er I mean selected, by the spec and then revealed by the magician in a much bigger way go over big. There are two approaches to that- a time sensitive prediction made before hand such as a mailed letter, interoffice memo in a manila envelope, Classified Ad from that day's newspaper, etc. or an off the wall revelation such as "card in (whatever you can dream up)", etc. Anything that doesn't involve the revelation being involved with yet more cards like an ID and the like.
