[marvel/dc] what are the best ways to get powers?

Easiest, cheapest, or most reliable ways to produce supers.

If you are in the Marvel Universe, and are a really shitty person, you can always use Mutant Growth Hormone. You get high, and you get temporary mutant powers as long as the high lasts. Of course, it's made from dead mutants, so it's highly illegal. 

Most other 'science' sources of powers in the Marvel Universe require you to have latent superhuman genes in your DNA already - that's what makes some people get super-powers instead of cancer when exposed to radiation or cosmic rays. So if you don't have that, you're out of luck on that side of things. 

On the other hand, anybody can learn magic! It will be a long and difficult learning period, but you will have super-powers at the end of it if you work hard and apply yourself.
