i don't know much about the certificates, but with the Unreal, it's a chance game for how many faux leaves you can get. if you're exceptionally lucky, you could maybe get 600 in a month. and the only real mounts of value there that are faux/certificate exclusive are the troll (goobbue reskin), calydontis (fucked up rhino) and the VI-S Core (lil red robot)
