Scaffold Stacking is an opener created by Winterfrost to reliably execute a King Crimson setup. Credits to Aotaku1039 for helping out on the third bag.
First Bag
The first bag is stacked like below. Holding J is ideal but if you want to increase the setup rate you can place it on the left side of the setup and still guarantee a 2nd bag T-Spin Triple.

Second Bag
The second bag is relatively simple, the first setup is ideal but sometimes you'll have to settle for the compromise. If you placed J in the first bag you only need the J before O setup and the compromise.

Third Bag
For the ideal path, you only need four setups to guarantee an STSD.
