Not done very many myself and I know some will disagree with me but this is how I like a show I am watching to go;
Short, hard impact starting trick, I am a big fan of sponge balls.
Pad it out with some that you know well and like.
End on a high, something you will be remembered for. Try a twist on something classic.
I like acts that do a bit of this and that, but if you want to follow a theme I do like acts that start with a trick that doesnt get figured out till the end. Things like predictions sealed in an envelope that gets opened at the end.
I liked the floating glass when I saw it once and the guy poured the liquid from a bottle into the glass then took the glass, poured the liquid into another glass, turned that glass upside down and a silk fell out and the liquid vanished. He used Tango (green apple Tango bottle, green food coloured liquid, green silk). I thought that was a good choice because it added colour to his performance. One thing I didnt like (being as picky as I am) is seeing all this liquid go into the floating glass but the level of liquid not rise as much as it should. I know its picky and hard to avoid but I do think he spent too long pouring into the glass because you stopped focusing on the illusion and focused on the liquid.
From a pyschological point of view, the human brain is almost set to remember the start and end of something most so that needs to be where you make your main impression (in my opinion).
A lot also depends on what you like, know and of course your budget if your shopping for new things. Good luck with your show

Magic is real, just look around you, some of the most amazing things have no reason, no explanation but are very real.
