I am learning a system for a card game that requires me to remember a deck of cards in under 5 minutes… amongst opther things.

Problem I have is that I am struggling to do this. Myu best time for totla recall is 9 minutes. This is using tested memory skills as outlined by Lorraine, O’Brien, Buzan et al.

I have recently started going to meditation classes as I receognise that there is probably a lot of benefit there way beyond my card game needs!

Can anyone help with ideas?
