These will realistically only work on US version. You can try JP, but expect quite a bit of failing passing between tournaments.

Firstly, there is some element of frame-perfect in this run to begin the run. The first input required is when confirming your name and this will select your deck. Importance of your deck is minimal, but it can help to have Level 1 monster dice beyond the guaranteed ones. Guaranteed dice we use from the pool are Baby Dragon, Shadow Specter, Twin-Headed Dragon, Kuriboh, Mystic Horseman and Pumpking.

Beaver Warrior, Penguin Soldier, Giant Flea, Witch's Apprentice and Mushroom Man are among the Level 1 monsters you can use that don't have an effect when summoned.

The second frame perfect input happens when you select 'Tournament' from the menu screen. If you hit this right, the seed will be fixed by actions until the conclusion of the current tournament. I would suggest following the timing used in my latest PB. You are looking for the two starts listed in Tournament 1 sheet of the link below.

Some frames nearby have the same enemy and going first, but you'll soon understand if they work. Once you hit the frame, follow the notes through to the completion of the tournament.

Frame buffer/advance means pressing B to cancel back to the field and press start to return to dice selection screen. This advances the seed by 1 for each Baby Dragon (or other flying monster) summoned on the field.

Fake dimension means going to the field, then pressing B to cancel back to dice selection screen. This advances the seed by 1 for each Baby Dragon summoned on the field.

Fake move means pretending to move Baby Dragon by a square, then cancelling. This advances the seed by 2 for each fake move i.e. once for each time Baby Dragon changes square.

At the end of a tournament, the seed begins to fluctuate on the Tournament Win screen. The strategy I use is to mash and leave the Tournament Win screen as soon as possible. I tended to hit one of three seeds - Early, Middle and Late one. Typically, I was hitting about 70% middle, 25% early and 5% late in practise. Some tournaments don't have backup routes for early and/or late seeds, so you will either have to reset or continue blind. You can surrender and buy the traditional Penguin Soldier route from Grandpa's shop.
