Multi Ball-Basic Poke Balls...but three of them. If it fails, then the next ball hits and tries to catch. If that one fails too, the final ball tries to catch it as well. 1x modifier

Foil Ball-You throw a completely random Poke Ball. Has a 1/300 chance of getting a Master Ball, but even odds for all other balls. Modifier equivalent to what is thrown.

Crit Ball- High chance of Critical Captures (but less so against legendaries) 1x modifier, 3x chance of crit, 1.5x chance of crit against legendaries.

Great/Ultra Premier Ball- Buy 10 Great or Ultra Balls, and get a stylish premier ball that is the equivalent of the one you bought!

Type Ball- Greater chance of catching Pokemon that have the same type as your current Pokemon. 1x standard, 3x when one type is the same, 6x when both types are the same.

On 12/02/12 I said I wouldn't change this until something impossible happened. Now, Earthbound just got re-released in the US.
