When I got this scramble I thought it would be the best in the set by far, turns out I was about to be proven very wrong... Mallard says the only way to beat 21 on this scramble is to do 11 to DR, so eh

This slice can be made into 18 like this: L’ F’ L’ (F2 B’ U2 L’ B2 L)//4b2 (9) (** Bw L2 D2 R2 U2 Bw)//make it off by 4x on S (D2* R2) *=E2 **=M2//solve in 18, cool thing you can do when it’s 4b2 8e like in this case, but I forgot about it :( Other DRs: B2 R’ D2 R’ U2 F L2 F//4b2 (8) (D2 F’ D2 F) (U’ R U R)//2c4 (8) (B D2 F2 D2 B’ R’ F2 R)//4b2 (8) Wtf is that EO count lol. For the EO skip axis I basically wrote R, L, F, B and (R), (L), (F), (B) and treated them like 1 move EOs to find RZP off of. I also switched F B, R L, (F B), (R L) and a bunch of the R F B type stuff before time ran out. Also the final solution for the 6 to 2c4 needing reduction into 2c3 6e is kind of cringe tbh By the way, this scramble is 15 optimal :O
