A simple and fun 2-packet cut that has isolation element in it.

Discovered the move on a video call with Duy & Hung. When Hung randomly said something along the lines of I wish I could spin two cards in one hand. I attempted it and figured out the core mechanics within minutes. Simultaneously felt very blessed to have discovered it and cursed to be obligated to perfect it. I also blame Shiv for pushing me to do the move with packets. Wasted a lot of my time on this detour. As a result, I still have not built an iso routine around Double Barrel. - Daniel Lin
