Don’t get me wrong, they’re gorgeous-looking – it’s one of the few good things about them.
In the history of Gems, though, we’ve only ever had circular Gems, skull-shaped Gems (incl. Holiday Gems and Doomskulls), and the square Stone Blocks.
Maybe it’s just me, but I find myself conditioned to see all non-circular, non-square Gems as matchable.
I look at the following image, and I’m more drawn to see the bottom Doomskull as matchable than the Purple Gems (with the Lycanthropy one):
Tbh, it gets a lot messier than that, and there are much better examples.
It would be great if the Lycanthropy Gems actually had some kind of circle around them, to make a board smattered with a mix of Skulls/Doomskulls and Lyc. Gems less confusing.
If necessary, maybe a brief, little, dull flash around the Gem as it’s changed from Purple to Lycanthropy could be added to highlight it, so it won’t be missed.
