Shadow Cannon

Shadow Cannon is a set of continuations found by westl from the first bag of Gull Wing TSD. The dependencies are I before Z and L before S, or if mirrored I before S and J before Z. It can be used as an Anti-Perfect Clear opener due to the fact that the first TSD can be built quickly, or simply an opener that sends a quick attack at the very start of the game, like Stickspin.

First Bag
Setup rates are 43.33% on one side, or 57.22% when counting both orientations. This resembles the first bag of a TKI 3 Opening, except for the fact that the Z/S piece is placed vertically.

Continuations
These continuations are grouped by the first piece of the second bag.

Early S Piece
I -> J This can be stacked most of the time. It will fail if S and T come before both L and J shows up early. The fourth bag can be stacked in one of two ways. Note that only S and Z need to be placed for the T-Spin Triple to be complete.
