In response to this article, Gastly is the worst Pokémon IMO. He has 
only 30 HP, and Destiny Bond is pathetic. To discard an energy to save him 
for one turn. Ha! I don't know who you fought, but everyone knows not to 
faint Gastly when it uses Destiny Bond. Gusts of Wind and Pokémon that use 
paralyzing powers eaisly take care of "The Great Gastly". I don't mean to 
sound negative but how a Gastly is good (unless it evolves) is mind-boggling. 
Thats all I have to say about that.
