Note: Both of these solutions and my quality of play are worse than in the original video.

First solution is a self-made C8u solution.
Sequence: I'PP-PPDD | PSD/PDcc | IPP-PPDD | PSD/PDT | PD/A'SDA | PPDDccc ( 13 | 6 | 13 | 6 | 6 | 6 )
This solution is by far the easiest of the 3 but it can't deal with jacks at all so I had to ban them. 13s waves have a 1.5s window where jacks can blow up the twins which is way too large to be considered acceptable.
I would place this a high level 11 or maybe a low 12 on the skill standard

Second solution is the old ch9 solution created by sellfish
Sequence: PPSSDD | PPSSDD | IPP-PPDD | PSD/PDcc | IaCP-Pd/PD | PSD/PDT | PD/A'SDA | PDD/PD | PSD/PDcc | IPP-PPDDDD ( 6 | 6 | 12 | 6 | 13 | 6 | 6 | 6 | 6 | 12+ )
This solution has a pretty high difficulty in my experience. I played completely terribly in the video.
The second ice wave has to be 13s because of the cob wrap which can't deal with jacks like explained before. However, two 13s waves per 2f is much better than 4 so it's more acceptable than C8u.
Hydroxyl made a new ch9 sequence with double 12s waves but it forces cob replacement so I didn't play it.

0:00 - C8u
5:03 - ch9
