Some rumors there will be an upgrading card event coming, possibly on March 12 or March 13.
I suggest you stop upgrading your cards right now, and save them for that coming event.
You can activate new cards, but do not upgrade old cards.
If that date passes by and still that event didn't come, then just use it.
