DR overload and the only possible sub-21s are very hard from the DRs I got...

i also had a few 10 move DRs with good subset but I'm lazy to type them

there's 21 from F R2 B U' B2 U to DR but you have to do a +2 extension to the 4c2e trigger and I didn't try that rip

I first found this 21 to slice:

(U2 R D2 R')
(D2 F2 U D R2 F2 U' D)

but it was really bad, then I came back to this HTR at 55 mins and found the other way to solve it :)

21 is optimal from EO yay
