SEALspin (or Super Evil And siLLy spin) is a TST > TSD > TST opener invented by Coolkat. The opener takes 6 bags to fully execute and results in around 18 rows of garbage sent to the opponent.
Please note that this opener is quite impractical and most likely won't win you any Tetra League games. This opener was created purely for fun and as a result of extreme silliness.
Bag 1
This will always work as long as the O and L pieces appear relatively early in the bag.
Bag 2
The I piece must come before the T piece and the S piece must come before the L piece.
If the I piece comes after the J and O pieces, it can be soft dropped and then rotated clockwise to fit into the gap.
Bag 3
The T piece can always be placed as long as both the S and O pieces have not been placed before it.
The J piece must be placed after the S piece.
Bag 4 (TST)
This bag and everything after it can be freestyled, but this is the recommended setup for the 4th bag.
If you use this setup, J must come after O and S must come after Z.
TST Execution
The technique used for executing the TST is outlined below.
Please note that CCW means Counter-clockwise in this scenario.

Bag 5 (TSD)
Like the previous bag, this one can also be freestyled.
Using this setup, however, gives you a wide array of possible continuations.
You could perform the t-spin normally, but it looks much cooler when spun upside down.
If possible, you can save the T block for the next bag.
Bag 6 and beyond
There isn't a dedicated setup for bag 6, but here are a few possible piece placements that can be done before executing the TST.
After the T-spin
After making the final TST, you can place either an L or I piece to fill in the hole.
From here, you can try comboing singles and doubles in a 2 wide, or set up 6-3 stacking.
Happy Sealspinning !!! 🦭
