As I get a higher chance of maybe an answer shortly after the post was made, I repeat my question (rephrased)

QUESTION Hive account@steemmonsters (or at any other who may can answer it like Hive account@flauwy Hive account@oliverschmid Hive account@holger80)
"Experience is gained by combining duplicate cards. A green bar indicates your progress to the next level." (quote from how to play)
Is it possible (like formerly was said) to gain experience (XP) via playing somehow or has this idea entirely been removed and XP gaining one by one does not exist as a concept anymore; you can only do it via buying and then combining cards?
