This.
But this is fun to just screw around with.
I know, but I'd make one for Blockland itself.
I dunno, maybe a server mod or something, who knows.
Maybe you randomly find cards by playing on servers with this (like Pandan's hat dropping thing)
And then you get a random card, some with higher rates then others (GreenBH)
and card colour rarities, like Green,yellow,orange,blue,red,black,silver,gold whatever, something like that.
But green first.
