Yeah, this is a solid use case situation that actually makes sense to me, since right now even unique Pokemon can be cloned and traded - I have a number of cloned event Pokemon in my collection, because they were events held in geographically impossible locations, and generous players distributed them online.

But I suppose that's why, even though using blockchain to enforce uniqueness on Pokemon is a genuine use case that I can see the potential value of, there's elements of it I'd hate if they were implemented. I've never been a huge fan of artificial scarcity, and using blockchain only makes sense if artificial scarcity is to be enforced. Right now, Nintendo seems to disapprove of cloning event Pokemon, but generally turns a blind eye to it outside of the official competitions.

So it'd definitely be a trade-off. Is it worth knowing for certain that your Zubat is 100% unique, if it also means that you can never "catch 'em all" because an event-only Pokemon was only available at an event 300 miles away?
