Hi,
You can always go to youtube and search for cardistry tutorials. It is good to start with basics and then progress into harder moves.
I have a youtube channel for teaching cardistry:
https://www.youtube.com/channel/UC2NjlIc3L9jvqCu_x65IQHA
other alternative is of course school of cardistry -youtube channel. they have good tutorials also.
It doesn't matter much what cards you use, but as the Virts say, best deck for cardistry is the one designed for it.
I would recommend using
Aladdins,
Tally Ho, Bicycle, some Ellusionist decks,
TheVirts SS16,
Fontaine, Chicken Nugget,
NOC decks, Zen and many others. Aladdins are great for beginners because the packets hold together better since they have a smooth finish.
I hope others reply too so you'll get more knowledge
Sincerely, Ilmari
