[DISCUSSION] what is the best breed able pokemon

[boazisg]

Ok I am actually breeding a egg move bulbasaur, and I am tring to teach it giga drain. the father is a serperior with leech seed, leaf tornado, slam, and gigadrain, the mother is a bulbasaur with tackle and petal dance. the child is always a bulbasuar with tackle and petal dance, so why doesnt it know giga drain, it is under egg moves in bulbapedia but it doesnt know it when hatched. do I need to do something to teach it more then one move?
