A Mini Triple Double or short MTD Attack is a class of openers where you start the game with a T-Spin Mini followed by a T-Spin Triple and a T-Spin Double, usually by using the first 3 T pieces. It behaves similar to STD Attacks (see Mr. T-Spin's STD and pwn's STD), with the difference that the T-Spin Single is substituted with a T-Spin Mini. In both cases, the single line clear is used to prepare a Triple Double Attack (also known as C-Spin). T-Spin Mini instead of T-Spin Single sends less lines but it can result in a higher chance to achieve a Perfect Clear after 8 cleared lines in total. Note that starting with a T-Spin Mini doesn't send any lines in most games but it will enable the back-to-back bonus. However, there are also games like Tetris Battle or Tetris Online Japan where T-Spin Minis will send a line and where T-Spin Triples are especially powerful with back-to-back bonus.
Joystick
Joystick is one example for an MTD Attack. The name originates from the left part of the setup after the first bag: the L+J piece combination forms a shape which looks like a Joystick. Note that L and J can be dropped in any order; the only important thing is that O piece must be placed before I piece in the first bag.

If possible stack the second bag like shown below (resulting in a T-Spin Triple). The first pieces of the third bag can be used to fill the bottom 2 lines to get a T-Spin Double (thus Mini Triple Double). With some luck you can also get a Perfect Clear: 75 % of all third bags can result in a Perfect Clear after getting a T-Spin Single (sometimes even Double). This chance increases to 82 %, if ignoring the T-Spin line clear.

Here's another way to clear a T-Spin Triple at the end of the second bag (in case you have to place J before S). However, this one is worse because it leaves an even number of cells empty below the T-Spin Triple. This worsens the chance for a Perfect Clear after 8 lines. In fact, there's no way to get a T-Spin Single (or Double) and a PC both at the same time. 44 % of all third bags can result in a PC , if not going for the T-Spin line clear.

TD Parfait
The following setup is called TDパフェ in Japanese, pronounced TD Parfait (TD = Triple Double, Parfait = Perfect Clear, note that parfait means perfect in French). It's another example for an MTD Attack. One interesting thing about this opener is that the T-Spin Triple can be stacked with its mouth facing both sides. Preparing the T-Spin Triple with the J piece (first 2 options) is favored because this will give a nice chance for a Perfect Clear after 8 lines.

In case of the first option, 76 % of all third bags can result in a Perfect Clear after getting a T-Spin Single (sometimes even Double). This chance increases to astounding 96 %, if ignoring the T-Spin line clear.

In case of the second option, 66 % of all third bags can result in a PC after getting a T-Spin Single (or Double). This chance increases to 85 %, if ignoring the T-Spin line clear. However, those PCs are usually hard to spot, if T piece comes late in the third bag. There are many options but none of them offers a significant probability. Note that L piece can be placed after Z piece in the second bag.
