Play more Repair maybe?

Arc Aura is quite a good options too. And I think 3 of Enigma Aura in Rainbow Ulith is good, I've never play the deck though, but I think it's better to having those good Life Burst cycles through your Life Cloth.

This is just random thoughts from someone who's passing by, you should wait for someone with more intellegical to come.

Ps. I think Blitzer-san wrote something about this in http://selector-wixoss.wikia.com/wiki/User_blog:BlitzerRyuusei/LRIGs,_Their_Abilities,_and_Their_Deck_Composition so you might want to check it out too.
