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%)
|
|
If the Z piece is placed, you can spin the I inside by doing the following: |
Rotate clockwise |
Rotate clockwise |
Move to the right |
If the L piece is placed, you can spin the I inside by doing the following: |
Rotate counterclockwise |
Rotate clockwise |
Move to the right |
If both pieces are placed, you can do both methods to spin the I piece in.
Hold J. 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 mirrored version of the first and second bags 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.
Alternate I (93.88%)
|
|
|
If there is no overhang, you can spin the I piece as follows: |
Rotate clockwise |
Rotate clockwise |
Move to the right |
If there is an overhang, you can spin the I piece with 180 rotations as follows: |
Rotate counterclockwise |
Rotate counterclockwise |
Rotate 180 degrees |
Rotate clockwise |
Soft drop |
Rotate clockwise |
Move to the right |
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 main 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 main route if you can instead.
Sixth bag (TSD)
Normal route
Left J (87.38%)

Right J (80%)

Alternate S
Left J (52.22%)

Seventh bag (TSD)
Left J (50.27%)

You can mirror the JOL/LOJ box.
