EPIC. I do a somewhat terrible bottom deal as part of a packet trick, I cover the front of the cards for a fraction of a second and pretend to pull off the top card, but instead pull away the bottom one. It works in the context of my effect, but there's no "push off" action which really sells the illusion. I think in a way gambling demonstrations are the exact opposite of magic - magic depends on secrets, whereas with demonstrations, the more you know, the more you freak the fuck out at the sheer skill.
@@mohammedraiyan9254 This is the cliche but it clicks at some point. I thought the bottom deal was an impossible deal for me 'cause I practice so much and got basically no results. Practice daily and your fingers will slowly develop without you realizing and one day it will be second nature to push the card without messing up the whole deck. I would say look at different grips and find the most comfortable one for you and watch different tutorials to get an understanding of how people do it because many people do it very differently and even the smallest change to your style can go a long way for you to finally understand and learn how to do it.
