thanks for the explanations!
how can I play?
when I get to my account on https://steemmonsters.com/# I see my collection but nowhere to play
when I login to https://sm.mrosen.com/# I only have the base cards and cannot see or use my collection
and battle! doesn't work (neither practice nor rank), I cannot see/choose any cards there

also with the RCs (other comments) would be terrible but anyway

besides, I just checked.
the problem I had which I articulated in my post is resolved :). what I wanted to do did work now :).
