Ok, so one player at a time in specific order can do all those actions - up to two discards and play, put tarot.
In my opinion it is better wording the way you described it to me now.
I was confused by 'decides to play or discard' as it would mean you do only one of those things. If you can do both of them, then why do I need to choose if I will have to play anyway?
Thank you for clarification! I haven't play it yet but I can't wait to! :-)
I will include conbini.
