The drop rate is so low that I doubt anyone can really confirm it statistically. :)

I have collected all the material cards for 2nd GUR except Little Shion. I could not recall where I got each of the material cards (advanced or extreme) and I don't plan to go to intermediate (only little shion can drop)  for potentially higher chance (still very low chance anyway) of getting Little Shion. XD

The side cost of tower events is all the leftover cards that need to get amalgamated to be useful.
