Strategy:
1. Clear his Monster Zone every turn (either by killing his monsters or sending them back into his hand)
2. Use Gravedigger Ghoul or Pot of Benevolence every time there are 2 Monsters in his Graveyard
3. If he steals any important card for the 9999+Dmg-Achievement (Piranha, Kangaroo, Koala) take it back with Exchange or if he sets it just 🔥 it and use Pot of Benevolence to get it back
As long as his monster zone is empty, Bakura will not use Ectoplasmer and he won't be able to summon Dark Necrofear with 2 or less monsters in his graveyard.
There are only two win conditions for him, making it only ~85% WR:
a) You draw very bad/unlucky and don't get any Ghouls or Pots 4 rounds in a row
b) He uses Exchange on his first turn and takes Blazing Inpachi from you... -_-
His response is to have another monster other than master and Piranha in the last turn to run over his only monster before attacking with Piranha buffed, so basically you do not need secret pass
