That's irrelevant, what he listed were EXAMPLES. The restriction was "any cave or cavern-like area". Abusing loopholes is one thing, but reinterpreting the rules to your advantage is another.
You are challenged to beat Drayden without using any steel type Pokemon, Dragon type moves or Ice type moves. Basically, no type advantages; just brute strength. Good luck! You'll need it... unless you over-level like crazy which is just taking all the fun out of it for yourself.
He said he wanted it hard :P I can see a few ways to do it myself already, so don't be so quick to dismiss it as impossible!
