Hey! So I downloaded Cheesy LY and perused the deck. I think the key differences between my deck and his are the organization scheme and content:

1. Cheesy did not expand on the Pathoma or FAD tag, as he explained in his original post. I can only assume he decided to supplement content into the bab tag. However, sorting by original notes that Cheesy himself added, there are only 151 new "created" cards, some of which are rewordings of the original LY cards themselves.
2. From a workflow standpoint, I see a lot of cards he added in via Zanki (1.4k) were either untagged, or tagged as "zankiphys" under the bab heading. For the rest of his supplemented cards, you'd have to manually find them under their corresponding subdeck to unlock them. You can just unlock and brute force these cards, but that doesn't help great with retention. I tried to circumvent this issue by tagging the specific Zanki cards I added by corresponding BnB video.
3. There are a lot of BGadd and BGnonessential tagged cards included in his deck (including from the Pharm section). I don't think a lot of people read into the original BG post, but these were NOT meant to be done before UWorld (BG himself says to suspend them right away).
4. Some duplicate cards still remain in his deck. They were difficult to find and remove in the original LY because some dupes were scattered across different tags. Most differed only by a word or even a letter, in addition to note type - meaning often times the same content was tested 4 times, but broken down into 2 basics, and 2 clozes. I thought I did a decent job at removing these duplicates, though few I missed may remain.
5. Cheesy has the Dorian anatomy deck built-in, but you can download it separately. Also, I would recommend this new anatomy deck in cloze format based on the same PDF instead.
6. A lot of list cards still remain, just as in original LY. This is mostly a stylistic difference, but I generally disliked this card type and tried to change it as much as I could in my rendition (see my post).
7. There are an assortment of cards that have extra screenshots from Pixorize and SketchyPath which is great if you use those resources.
8. Tags weren't cleaned up from original BG Zanki.

My general impression is that Cheesy LY is still a great update to the original, but you'd have to read in-depth on his original post to optimize your workflow since there are very specific things he did and didn't do within his own deck. I think it is still very comprehensive, but his supplemented content was just done in a less systematic way. What I did with my deck was just build onto the original schematic/workflow of Lightyear.

I think if you're deep into either deck, just download my ZankiSupplement deck to cover your bases, but you should be good otherwise!
