I've uploaded what's out so far of Modern Horizons. No promises, but I plan to do a handful of incremental updates as the set is spoiled, so you can get to brewing.
Some cards are still very low-res, or in various foreign languages. As a reminder, if you hold ~ while mousing over a card, Lackey will display the full text info.
P.S. War of the Spark images are now high-res too.
Full set is up.
Two more things I've noticed.
Couldn't be less important, but 8th Edition Island is a broken image.
While trying to make a Gishath deck, I discovered that in Urza's Saga; Shivan Hellkite has image 214, which is Shiv's Embrace, Shivan Raptor has image 215, which is Shivan Hellkite, and Shiv's Embrace has image 216, which is Shivan Raptor.
Oh hey, I was just reading that Scryfall changed the numbering for some old sets (which don't have official collector numbers). I bet that's causing the mismatched cards.
I should probably do a bulk re-download and I bet it'll fix almost all of this stuff.
I downloaded/saved/uploaded a fresh copy of all the plugin's images. Everything mentioned seems to be working properly. Thanks again, and let me know if you notice anything else amiss.
