Hummingbird

Hummingbird (formerly Subscriber Special) is a quick and efficient T-Spin Single opening setup for early S/Z bags. It only requires 5 tetrominos to execute, and can easily be followed up with an STSD. L piece must be placed after completing the second line.
== Build Order ==
In order to build the Hummingbird with an SZ start, it is required to place exactly one J piece or L piece before the T-Spin Single. The I piece can be placed after the first J/L in its respective position regardless of whether it comes before or after the T-Spin.
		
In cases where both J and L must be placed before the T-Spin can be executed, a similar setup can be used. Note that in the following example, the O block is on the left side of the T-Spin, thus it is essential to know the queue before choosing this setup or the Hummingbird proper.
== STSD Transition ==
The following setups cover most circumstances when transitioning to an STSD.
				
=== After the TSD ===
Other than making a T-Spin Double, the TSD can be converted to a T-Spin Triple, Imperial Cross or Trinity. 2-7 stacking and 4-Wide are also possible.
		
T-Spin Triple	
Imperial Cross	
Trinity
== Early J and L ==
	
After the T-Spin Single, the setup is usually continued with an Imperial Cross. The first two setups have a decent chance of resulting in a Perfect Clear, but the third setup should only be used for unfair bags, which cannot result in a Perfect Clear.

Second setup: 1 solution (Both TSS and Tetris can happen)
