Okay, picture a hill, a big hill, yall want to be on the hill.
Say what your gonna attack the hill with to get rid of the previous persons defences (and why it would win) and then say what you are gonna defend with:
For example if the hill was being defended by a snail:
I attack the hill with a hobo, who eats the snail
I defend the hill with a hobo, armed with a rusty tin can
No nukes or Chuck Norris, and your not allowed to do anything that would destroy the hill.
Okay, so lets start with my hobo defending the hill...
