I'm honestly very glad the card isn't obtainable outside of aflatoxin, it would be incredibly overpowered otherwise.
But this thread's given a minor concern. If I somehow obtain an "illegal" card through a bug (NOTE: *not* attempting to abuse a bug, it just happens) and I keep the card for the novelty of it (But never, ever use it under any circumstances. Ever.) am I breaking the rules? Can I be found out and banned? Alternatively, If such a thing happens and I report it to Zanz, is there a chance of my account getting reset/banned?
