I've got to give you this : The Repulse control you did is absolutely amazing! I haven't seen any flashes, it looked like you just squared the deck up, great job! I have no critics on the trick itself , tho I do have on your videos :/ Add some music, or if you're from America talk in your videos
Make up a story! And I will end with a quote from a world famous cardican "It doesn't matter if the trick is simple or hard if its visual or not what makes an effect magical is how the cardican presents it" -Dai Vernon
