Solve Crazy 3x3 Plus Mercury with my "Corner Last" method.
Steps/algs
0:00 Scramble
0:25 Edge centers (layer by layer)
Algs: RU'R', L'UL
1:09 Edges (layer by layer)
Algs: first layer - R2 U'R2, RFR'F', second layer - RU'R', last layer - [F:[R,U]], RU2R'URUR'
2 edge swap case (parity): x2 RURUR U'R'U'R' R'U2RU2 x2 F2 L2 U' F2 U2 L2 U'
2:13 Corner centers (first layer)
Algs:
F2 [RUR',D] F2 - from U (up) to D (bottom)
F2 [D, RUR'] F2 - from U (side) to D (bottom)
B' [R'D'R, U'] B or B [LDL', U] B' - from U (up) to D (side)
5:15 Corner centers (last layer)
Algs:
R2 [RUR',D] R2 or L2 [L'U'L, D'] - from U (up) to U (side)
6:02 Solve corners (layer by layer)
Algs:
[ULU', R] or [U'R'U, L'] or [R,U] 3 - first layer corner solve
[URU', L'] - last layer corner permutation
[[R,U]2, L'] - last layer corner flip
