This stops you from doing things like delaying an attack by 7 frames to get a different drop or anything.
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.
The seed also changes whenever the game calls for a random number. In particular, the game calls for random numbers whenever it performs certain animations, and this includes most animations that happen in a duel. 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.
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.
