As cool as that would be, breeding doesn't work like that. Every Pokemon has a set of moves that they can learn through breeding and sadly Precipice Blades is not one of them.Would it be possible to breed precipices blades onto a garchomp by
1. smeargle sketch for original move
2. Breeding with an ekans to get precipes blades onto the dragon egg group
3. Breeding smeargle with grachomp to get garchomp to learn precipes blades and therefore a better stab ground type move
Just thinking about this in theory
