Been awhile since I did anything semi-serious TAS related for B/W; since I only beat the main storyline in my run I still could beat the improved E4.. why not?
I've figured out a little bit more of the move-choosing logic the game uses and its strategy. It always prefers to Fake Out if it has it, then hit you with the highest damage move (usually STAB).
Only when you are low does it try to "finish you off", and the move choice is pretty random
. Just one battle took a lot of planning!
gonna keep going at this over the next week; recorded the one battle I've done (probably the most crucial)
battle RNG so stronk
