Tricks

first you must know how to do a heelflip and a casper.
if you do heres the rest first do a heelflip and when you land it you could either land it into a casper pop it up and land it or you could do a heelflip and land it and quickly put your foot at the edge side of your board and flick it back and land it into a casper,
If you want it a harder challange try it doing a 180 or a 360.
