i also remove the jokers and ad cards.
some people prefer to use less cards. it´s nothing wrong with it.
some people use a few cards more for practicing
so everything is a bit easier with 52 cards when performing.
or like already mentioned some use less cards to get used to new grips.
the deck i´m using at the moment the most (for flourishing ) has 48 cards.
because i don´t care anymore if i don´t find every single card after dropping them.
(there are quite a few cards under the sofa, bed etc.
)
i had a phase were the deck just didn´t feel right to me if a card was missing.
i guess over the years i got less serious about flourishing. which feels better.
