There is no right or wrong with routining as far as whether or not you wish to do several separate effects OR a routine which segues from one into another in a smooth blend. If you are just going to routine several separate effects together you just want to make sure that they are not the same thing such as 3 torn and restored effects OR a prediction followed by another prediction. Just start with a simple but effective quick effect and then build up to your strongest effect to close, one that will leave a lasting impression AND always bear in mind to leave them wanting more not having them wanting you to leave them alone.
If you use a segue from one into another, you might want to try something like opening with removing the deck of cards from the card case and have them vanish only to return to the card case. Remove them again and perform an ambitious card routine and finish it with "Solid Deception" (Paul Harris) or start by shuffling the deck, have the particpant cut to all 4 aces, perform twisiting the aces and then into Paul Harris' "Bizarre Twist" into something using only 4 aces transposing and no other cards OR McDonald's Four Ace Trick, followed by "The Invisible Palm" using the four aces, then moving into a Jack Sandwich type routine but using 2 aces only.
(Just having one effect flow seemlessly into another).
Some people that perform close-up set up in one corner and rather than table hopping, do set close-up shows where the audience comes to them as they want to. In that style, it is far easier to routine a show rather than doing a trick here and a trick there for a walk around situation.
you forgot Dr. Daley's Last Trick, its classic.
