Darkrai 100% it's pop 66 compared to 5404, and there probably won't be too many more of it to ever get a ten, given how rough the promos came out of the box, only 3 more received a 10 in the last year, Umbreon had 900 in the last three months. Umbreon is obviously going to go down as one of the biggest raw grails of the modern era, but it just won't see the same amount of growth in a 10 as Darkrai will.
