I think for most breeds - at least those in the cave - the easiest thing to do would be to discern rarity by market prices. Because, even though TJ refuses to acknowledge that, the prices shift with the ratios, and somehow must reflect them. Of course, when trying to catch something, supply and demand comes into play, leading to user-driven rares. But that's a whole other story.

If you look at market prices, you see that most dragons cost either 100 or 200 shards, these are obviously "very common" dragons. I'd suggest putting "common" dragons between 300 and 500 shards, and "slightly uncommon" dragons at 600 to 900 shards.

I know that their spriter once stated that Coppers are supposed to be uncommon, and their market price is always slightly below 2000, so I'd group everything between 1000 and 2000 as uncommon. This group would also include Golden Wyverns, Aeons, Gilded Bloodscales, Blusangs and Nexuses. If you want, divide it up to 1000-1400 (uncommon) and 1500-2000 (very uncommon) to divide it up. Everything above is simply rare (up to 2900) or very rare (above 3000).

Now there's the thing with hybrids and alts. All things considered, I'd declare the rarer alts as very uncommon, color morphs (tan ridgewing, red dorsal...) as uncommon. Hybrids and Zyus... I think I'd go with uncommon there, too.

Another thing I noticed is that breeds with different variants in different biomes seem to be priced way lower than their apparent rarity. Seriously, Xenos overall may be just shy of common, but each individual breed - nope. I'd class them one higher than their prices suggest, or add a fixed amount of shards for calculating which group they belong to.
