Maospin

Maospin is a setup which starts with a single line clear T-Spin Fin in the first bag, followed by a T-Spin Double in the second bag, STSD in the third bag, and a 100% Perfect Clear finish in the fifth bag. Unlike most T-Spin Fin setups this setup only clears one line in the first bag due to the setup not wasting the first T piece. This setup was made by and named after Maosense.

First Bag
The build chance of the first bag is 100% as long as I and O come early.

Second Bag
One can always stack the second bag like this.

Third Bag
If J comes early, building the stack below is always possible. One can always stack the third bag like this. This will still lead to a 100% Perfect Clear field but there are more solutions.
