How can we possibly get 800 shards in less then 18 days in Defining Legacies?

Luckily, I got a 109 Pirlo and had about 300 shards, so exchanged for a 111 Pirlo.  Used up 108 Essien from League exchange and 108 Ibrahimovic GK from Zlatan chronicles along with another 108 I had for the 111 exchange. And as someone suggested, his passing is sublime.
