Shadow Cannon is a set of continuations found by westl from the first bag of Gull Wing TSD. The dependencies are I before S and J before Z, or if mirrored I before Z and L before S. It In the best scenario, it can achieve Perfect Clear after 8 lines which leads into a potential DPC loop or Perfect Clear after 10 lines. It can also 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.
