You'll just be playing it like a dragon team with a higher damage multiplier anyway. And since I am sort of focusing on my Echidna's recovery, I think I can offset the -500 should she gets high enough with the levels and the +egg bonuses.
The only problem I forsee is the restricted orb changers. It looks like you are kind of forced to do either pure dark dragon team, or just go for 2 leader, 1 dark swords, 2 grass swords and 1 Echidna.
