The ghost touch weapon/blinking thing is very popular, but it doesn't work. I'd suggest reading the "There, not There" series of rules articles on the wotc website.
Also, I'm assuming that the energy drain/enervation combo you're using on different foes, because the damage doesn't stack.
And you can only have one contingency spell active at a time.
It would be interesting for someone to post something that doesn't rely completely on spells and having some indefinite number of rounds to buff yourself beforehand because Disjunction has a way of undoing all of that very quickly. My players found that out pretty early in my epic campaign.
