Sing got an accuracy boost in forth gen? well that completely destroys my argument. And I thought you were talking about Hypnosis/Dream Eater... Whatever disregard what i said, I was talking about First/Second/Third gen i which sing/hypnosis only had 55 accuaracy.... wow, im an idiot.... anyways, I still like hyper beam, and yes i do put blast burn on my charizard in firered. and its not like you use hyper beam every turn (although i did do that once when i was bored =D) i use it on water, fire, and dragon pokemon when blast burn doesnt cut it. if you raise your charizard/blazekin alot give it all the vitamins you can (basically what i did) hyper beam becomes much better.
I've also done the same thing to venusaur, sceptile, swampert, and balstoise.... so whatever.
