My baby sister is having a birthday party soon and I'd like to do a few cheap, fun magic tricks that I don't really need to have anything prepared(all I got is a deck of cards). Can anyone tell me a few tricks I could do at the birthday party + how to do them? Also, I need a really awesome, complicated trick to show my brother, because every card trick I try, he figures out without even thinking. Please if someone can help me out, I'd appreciate it.

Magic is like other art forms, there are artists and creators of tricks. While I'd love to share all the best tricks out there it would disrespectful to the creators out there if I did. The best place to start is the library or you could get a classic book like Royal Road to Card magic.

A common problem with beginners who have a hard time fooling others is the double lift. They rely heavily on a very difficult sleight. You can try to avoid tricks that use the double lift or you can work hard to improve the double lift. If this is your problem you might check out this post by Aaron Fisher
