MDPC is a stickbase opener that results in a T-Spin Single in the first bag, a DT cannon in the second and third bags, a TSD in the fourth bag, and a Trinity in the fifth bag.

First Bag (TSS)
Second Bag
Normal I (93.33%)
Second Bag I-Spin Finesse
- If the Z piece is placed, you can spin the I inside by doing the following:
|
Clockwise
|
Clockwise
|
Move right
|
- If the L piece is placed, you can spin the I inside by doing the following:
|
Counterclockwise
|
Clockwise
|
Move right
|
- If both pieces are placed, you can do both methods to spin the I piece in.
If the I-Spin is not possible but S can be placed before I, you can also do the slightly risky alternate setup (83.33%) that has a 93.88% recovery on the third bag.
It is also worth noting that in SRS due to asymmetric I-piece rotation, the second bag after the mirrored first bag actually has a 100% build rate and can be prioritized in certain games because of this.
Alternate I (83.33%)
When used with the main setup, this increases the chance of doing the second bag up to 95.23%, and 95.11% for the third bag.
Third Bag (TSD)
Normal I (100%)
You can rotate the OSZ congruent shape in four ways depending on the piece order.
Alternate I (93.88%)
Third Bag I-Spin Finesse
- If there is no overhang, you can spin the I piece as follows:
|
Clockwise
|

- If there is an overhang, you can spin the I piece with 180 rotations as follows:
|
|
Counterclockwise
|
Counterclockwise
|
180°

Clockwise

Fourth Bag (100% TST)
Hold J until after the T-Spin Triple.
Fifth Bag (TSD)
Normal route (78.33%)
Hold I. Make sure to do the T-Spin before or after placing both the J and L piece. If you only place the J piece then it blocks T from entering the well.
Alternate S (78.33%)
Combined with the normal route, this increases the chances up to 87.62%, but this route has a significantly worse sixth bag cover so when possible, it might be better to do the normal route if you can.
Sixth Bag (TSD)
Normal route
Left J (87.38%)
Right J (80%)
Alternate S
Left J (52.22%)
Right J (43.49%)
Seventh Bag (TSD)
Left J (50.27%)
You can mirror the JOL/LOJ box.
Right J (31.11%)
