Just to add to the SweeTar back variant conversation. Below is the back of the SweeTar Ludlow I just got from a sketchless box I bought on eBay from CardGarys. I've not analysed this box to figure out if it's otherwise skewed.
That is the variation I was unable to pull in 60+ boxes. I found a collector that is sending me 4 of them and one of those goes to Scot.
I think Scot and I will be the only ones with the lud variation sets. I can help out 2 more people if someone wants to get a variation set.
