Not sure how many folks use Richard's list for variations. He updates his list regularly from many sources including this thread as well as other posts on this board concerning variations that are not in this thread. In other words, his list contains more variations than just the ones mentioned in this thread. While I consider his list as an incredible resource as it is, there is one thing I would add to it if there was ever time on my end(there is not). That would be to add clickable links to images showing the variation itself on the card mentioned.
I have posted the link to his site multiple times, but here it is again:

For those who enjoy making trades, he has his wants and extras included also.
