Re: Shatterbird vs the Crystal Gems – Wildbow has said that Shatterbird doesn’t make grasses which contain silicon explode because of (her version of) the Manton Effect. It wouldn’t surprise me if Gems are covered as well. (Although they’d still have a really hard time with her – remember that sand-controlling pillow?)
I suppose that’s fair. Although we’re once again back to whether it’s organic vs inorganic or alive vs dead, which seems to depend on either the person or the power (Weld is unaffected by powers that exclude either side of organic vs inorganic despite definitely being alive, so we know powers like that exist, but Faultline was able to cut dead wood but not living wood, both of which are organic) – in the former case, grass counts but Gems don’t.
But yeah, the Desert Glass is absolutely relevant, and Shatterbird’s sand control seems to be vastly more powerful.
(I actually tried to find a video of the Desert Glass fight to use in this post, but couldn’t find a good one.)
