I'm just interested in how to copy a scrambled square-1(match the scramble). I dunno how to do it fast. I just have an idea as below.
First, match the shape.
Second, analyse the permutations of the cubies.
Third, go back and do the permutations.
Last, match the shape in the same way.
I'm very lucky, found the solution in just 6 mins. Another guy found the same solution in the last minute but failed to write it down:(
D F2 D2 F2 D R2 B2 L2 R2 U F L2 R F D2 F D' U2 B R2
R2 F U2 R F D' R' D' R2 D2 B' D' B U' R2 U R2 D R' D' U' R' B R U R' U' B' U (29)...
