Vrita/luci sounds like a good combo but i find earlyish game luci alone omgwtfbbqowns everything with his nuke anyway, and when it starts to reach a point where he cant, you will prob have access to gravity, which compliments him better, and is paired with better stats too.
Vrita's ultimate looks so cool though, honestly though, i think stat/cost wise, he just may have the worst ultimate in the game =p (excluding ones with silly drawbacks for specific purposes). Susanoo is definately one of those gods that everyone would benefit to have though, stalls, spikes, whatever. His active is just so good and useful. Spike teams can rely on it to survive one shots for decent lengths of time, and stall... Well duh.
Its really an amazing active that is good for any team against any foe (except ones designed to one shot anyone no matter what). Its kinda like a less potent active than ecchi's only it works against shield bosses too! Id say he's a great score imo.
