The Batzz (from Future Card Buddyfight) pack reward. Originally distributed on patreon(His page seems to be indefinitely under review), this pack was also put up for sale on the artist's gumroad(as of writing, it is still available for purchase there). However, this gallery does not include all of the "extra" images that are in the original/gumroad pack(which are the steps/drafts and some bonus sketches that I can't identify from the preview image from the original patreon(*cough*KP*cough*) page. You may notice that the "tied" sequence skips(look at the file names) I through L, and V. As far as I know, these six images don't actually exist, and the files are just named this way.

Pg. 1-15 are the "Shorts" sequence.
Pg. 16-17 are two "extras" (these might not be all of the extras of this particular sequence)
Pg. 18-40 are the "Throne" sequence.
Pg. 41-64 are the "Tied" sequence.
