IN pokemon Black and White can you encounter a shiny with max repel on?

No, you cannot encounter a shiny Pokémon with a Max Repel on in Pokémon Black and White.

Here's why:

* Max Repels work by preventing any wild Pokémon encounters. This includes both regular and shiny Pokémon.

* Shiny Pokémon are a random encounter. They have a specific chance of appearing regardless of any item used.

Therefore, using a Max Repel will stop you from encountering any Pokémon at all, including shiny ones.
