1: Multiple Spectator , multiple card (4-5 cards each spectator), prediction (mnemonica). This hits extremely hard, and can be even harder hitting if you do a deck switch after multiple spectators shuffle.
2: ACR finish with signed card appearing in an empty beer bottle on the bar counter 10 feet away (this is fun! muahaha, and its a reputation maker cuz I have only done it once, and I got the best reaction of my life, and people still remember me at that bar for doing it. Gotta love Japan).
3: Liquidsn's version of Blizzard (havent done this in a long time, but it totally kills).
4: Cyril's "Soroemasu / そろれます" a great trick based off of farro shuffles.
