Shellder is a Water type Pokemon that is quite rare in the fourth generation Pokemon games. There is only a five percent chance of catching one using the Super Rod at both the Valley Windworks and the Fuego Ironworks. It can also be found in Route 205, but again there is only a five percent chance of encountering one while fishing with the Super Rod.

It's not really that rare of a Pokemon. Shellder is a common Pokemon, and you can easily get Water Stones to evolve it.
Pokerus happens at random, it is about as rare a finding a shiny pokemon.
You cannot clone Pokemon and items on diamond and pearl and platinum, but you can in emerald!
