Master Ball -
In the games it is 100% guaranteed to catch any Pokemon without a single hit to weaken it ahead of time.
In the anime it's supposed to be that way, but is prone to getting eaten by Wishcash therefore defeating the purpose of this otherwise amazing Pokeball.
I thought that Sulivan guy was so creepy at first...
When the episode went on I still thought he was a creepy creeper, but he came to be more entertaining and funny. xD
