Ok, I need help deciding on something. I manged to get my hands on a Japanese event Hydreigon (long story). It's SHINY!
It came knowing Hyper Voice, Dragonbreath, Flamethrower, and Focus Blast. Flamethrower and Focus Blast seemed fine as is, I swapped Dragonbreath for Dragon Pulse, but I can't decide what to swap Hyper Voice for. Any ideas?
