// This is a tough scramble for me, and I will be using a color-neutral FB as a result.
y2 z // In this orientation, I see that F' will join together a corner/edge pair in DfL.
S // But I can do better! Instead of bringing down the corner, I can bring up the edge in DLS!
r' // this completes a cute little square, which we can then put back on our L layer with...
f' // dfR complete.
// we just need the back pair. I notice that my D center and B center are also aligned at this point. (dumb luck)
// The other corner is misoriented in UBL. It's gonna take me ~3 moves to insert it into the triplet.
// Since it will take a lot of moves, I'd like to join the corner with its matching edge while I am preparing it for insertion.
// The matching edge is in DFM, so pairing is pretty easy with:
U M2 // pair formed in UBr. But it's not oriented correctly, so I will have to mess up some centers to get it in quickly.
r B' // inserted into FB. FB is complete!
