Randomizer ensures any 4 consecutive pieces dealt are all different.
Notation +X-Y means X held, Y missing from next piece preview.

Case 1: One of each piece
Can be mirrored if J comes before L.
//TODO: Permutations that don't work with this build or its mirror image.
Case 2: +I-L, +I-J
Diagram for +I-L, mirror for +I-J.
//TODO: Permutations
Case 3: +I-O, +O-I
Use held I or O first. Make a 4x2 with I's or O's. With remaining L, J, T, clear depending on their relative order:
TLJ: (hold J until after second O/I if necessary)
TJL: Symmetrical to TLJ.
LTJ or JLT: Hold T, reduces to above cases.
LJT:
Case 4: +I-T
Use held I first, then hold the second I if necessary. Build depending on relative order of L, O, and J, then finish with I for a Tetris Bravo:
OLJ, OJL |
LOJ, JOL |
JLO, LJO
