To get a shiny Dratini in Pokemon Crystal you need to find one in the wild or hatch one. This is extremely rare though with a 1 in 8192 chance of the wild or hatched Dratini being a shiny. There is no way in Pokemon Crystal to improve these odds.
Defeating Pokemon that are a higher level that it, or Rare Candies.
If the card is shiny, the Pokemon is a high level, or both then it is rare.
Every Terrakion Pokemon card that has been printed is at least a rare. Each pack of Pokemon cards includes at least one rare card, though it may contain a second rare card as the reverse holo.
Yes Groudon is rare. It was the first Pokemon Card ever made. I hope you can get one. -Cosmo1128
