Also, since my first move will always be the same, I can only control the AI's first move by entering the duel on certain seeds, and at times this can reach odds of 0.2% or worse.
I don't have much flexibility here in a duel since I want to go as fast as possible, but at two points I dump a card for just this reason.
In particular, the game calls for random numbers whenever it performs certain animations, and this includes most animations that happen in a duel. The seed also changes whenever the game calls for a random number. Once you enter a duel, you are to a large extent "locked in" so I need to spend time setting up the duels I want. This stops you from doing things like delaying an attack by 7 frames to get a different drop or anything. The exceptions to this that matter for this TAS are loading screens and duels. This seed gets set to 0x55555555 at game startup, and then changes once a frame for most menus, dialogue, etc.

The game uses an LCG with a 32 bit seed (specifically the ANSI C one). On top of this, I need to draw the specific cards I want, the AI has to play a monster weak enough where after a suicide I can win, and then they have to suicide with it. Then I have to get some other drops (Mountain is a 1.7% drop, Jirai Gumo is a 0.2% drop, second MBD is a 1.0% drop). To pull this off requires a good understanding of the game's RNG and how this is used, since I am trying to beat an end-game level boss at the start, quickly, and get a 0.2% drop. An equip for MBD would also work, but starting with this takes too long and it also takes too long to win. For most of these I use a strategy suggested by GCAH2006 that involves Mountain, and it's quicker to win that from Rex than to try and start with it in your deck. These are Heishin, Pegasus, Heishin 2nd, Seto 3rd, DarkNite, and Nitemare. There are a few opponents who can see your face-down cards and so will never suicide. This means they beat everyone in three or four turns, which is the main cause for the gap between our times. In contrast, Hoandjzj's general strategy was to make a deck that can fuse lots of THTDs (Twin-Headed Thunder Dragon, the strongest fusion you can easily make) and win an MBD off Meadow Mage. There is no way to pull this strategy off without having an MBD (without it the fastest win is 3 turns, barring other strategies that would involve winning lots of hard to get cards), so the extra duel to win MBD easily pays for itself over the course of the World Tournament. It's ideal to do this without having to fuse, so I win Jirai Gumo from Weevil and later on I win a second MBD from Meadow Mage. This is accomplished by having the AI suicide into my face-down MBD, then attacking directly with MBD and a second monster. Dragon from Heishin, then beat most duels in 2 turns.
