Lancelot (Saber) team?

So I had a look at all the knights of the round table in preparation for Camelot, and found that Lancelot has a ridiculously crit heavy skillset... and I'm a complete sucker for crits, certainly going to try and get him if I get the chance.

So The question here is; What would be a great team for him? I have a few helpers that he might benifit from, like Jakku and Tamamo... but what would be the absolute optimal team? In your opinion.
