Midgame Opportunities
The Polymer (Trehalose) shape. At frame 3 is a Fin-TSD followed by a normal TSD (because the step is too far for Kaidan to work). It is a Fin-TSD at frame 11, followed by a Polymer (Fin-TSD + Neo-TSD combo, i.e. Trehalose). Explanation thanks to a random Tetris novice, and fumen thanks to Larrytetris; further pages will be created on Neo-TSDs and Fins to explain these elements.

FinT Cannon

 * ''Main Article: FinT Cannon

FinT Cannon is a setup that starts with a Fin-TSD to TST.

The Godspin
This is a little too extravagant to be doing for any other purpose except to "look extravagant". However, it is a decent exercise in understanding T-Spin polymer mechanics.

Godspin Setup Followed by Center 4-Wide
This setup works with nearly any bag: (TTL base)

When setting up Godspin in the center, make sure to only use two Z pieces in the stack, and the use the 3rd to create the floating blocks - any extra will cause stacking problems. Likewise, only use the first two T pieces in the TTJ base, save the 3rd for the first attack. If you have an early S in the 3rd bag, just place it on top of the S used on the side overhang, and wait for another I piece to fix the stack on the side (outlined):
