SPL
From Speedsolving.com Wiki

SPL is a method invented by Matilda Teixeira aka MatildaCruzzader25. The creator was inspired to make the method because of the fact that a team in the January 2021 Method Development Competition made one.
Steps
 EOSlice: Edges are oriented, while a line consisting of the DL and DR edges is formed.
 Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are built without regard to Corner Permutation.
 OCLL: The corners on the last layer are oriented.
 L6EP: Permute the last six edges. (There is a 50% chance of "parity", where you'll get 2 edges swapped at the end of LSEP. To fix this, you can do a Tperm or Fperm from the CFOP method)
 CPBL: The corners on U layer and D layer are permuted using one algorithm.
Variants
Beginners
 EOSlice: Edges are oriented, while a line consisting of the DL and DR edges is formed.
 Keyhole Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are built without regard to Corner Permutation and with KeyHole.
 OCLL: Orient last layer corners.
 L6EP: Permute the last six edges.
 CPLL: Permute last layer corners then do a z2 or x2 to permute first layer corners.
COLL
 EOSlice Edges are oriented, while a line consisting of the DL and DR edges is formed.
 Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are built without regard to Corner Permutation.
 COLL: Orient and permute last layer corners.
 L6EP: Permute the last six edges.
 CPLL: z2 or x2 to permute first layer corners.
Intermediate
 EOSlice Edges are oriented, while a line consisting of the DL and DR edges is formed.
 Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are built without regard to Corner Permutation.

Roux AKA RouxCP
 Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are solved like in Roux, but without regard to Corner Permutation.
 OCLL: The corners on the last layer are oriented.
 CPBL: The corners on U and D are permuted using one algorithm, Edge Permutation can be ignored.
 LSE: The last six edges are solved like in Roux.
Roux Beginners
 Keyhole Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are solved like in Roux, but without regard to Corner Permutation.
 OCLL: The corners on the last layer are oriented.
 CPLL: Permute last layer corners then do a z2 or x2 to permute first layer corners, Edge Permutation can be ignored.
 LSE: The last six edges are solved like in Roux.
Roux COLL
 Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are solved like in Roux, but without regard to Corner Permutation.
 COLL: The corners on the last layer are oriented and permuted.
 CPLL: Permute last layer corners then do a z2 or x2 to permute first layer corners, Edge Permutation can be ignored.
 LSE: The last six edges are solved like in Roux.
Roux Intermidiate
 Pseudo F2B: The first two blocks (F2L, but missing the DF and DB edge) are solved like in Roux, but without regard to Corner Permutation.
 OCLL: The corners on the last layer are oriented.
 CPLL: Permute last layer corners then do a z2 or x2 to permute first layer corners, Edge Permutation can be ignored.
 LSE: The last six edges are solved like in Roux.
Pros
Cons
 Relatively high movecount (6575 moves).
 The Edge Orientation step may be hard to get used to for beginners.
