If you could be any Super Hero and/or have any Super Powers, who would you be and why? would you use your Super Abilities for good or evil?

I wanted to have a super power of you can memorize things since the time u saw it because in grades 8's life, almost every day have assignment, quizzes, and test and we doesn't have enough time to memorize or understanding the stuff. And it also will be cool if you missing some stuff so you can use your” RECORDER BRAIN” to go back the places. I also wished that i have a super power of a magic stick that will have anything that i wanted and it's free* i know it's impossible, but that's what i want*because i wanted to have many things but it's so expensive so i think my parents won't buy for me, so i hope that i have the power, I also can help people who is poor that needed some stuff but they have not enough money.I will use my abilities on good. 

This is an example of my magic stick.
