Sewer

Sewer

Sewer (known as TZT砲 in Japan) is a setup that uses three consecutive T-Spin Triple attacks. Completion of the setup sends 20 lines to your opponent which is enough to fill their field with garbage. The reason this setup is not commonly used is because it makes the assumption that your opponent disconnected their controller in order to work. It is discovered by Yuu.

Full Setup Example

First Bag

You can build Sewer if your opening bag has a late I piece while you get the S/J pair before the Z or the Z/L pair before the S.
