User blog:Ra Ra Runi/Rainbow Ulith (Help)

Im having alot of trouble making a Rainbow Ulith deck. You wouldnt think it would be this hard but there way too many possibilities and that makes you second guess everything. My original plan was to run a four color deck but that makes her Exceed 5 easier to predict so why not run an rainbow deck and make it nearly impossible? The Lrig deck has four slots open to Arts since Ulith 0-5 is ran but to reduce the need for Black Signi Ulith 4 is Ulith Black Sand Enma and im highly glad its only 3 colors to grow to Ulith without having to pay it so if someone uses Fracturing Lust she can still grow.

Arts ive considered

 * Black Desire
 * Grave Gut  (currently saving for SP-03)
 * Mind Mines (Arc Aura users beware)
 * Grave Out (Hella expensive but for ANY 3 signi i think i could run it)w
 * Ancient Suprise
 * Idol Defense
 * Rainbow Art (Returns signi and a spell with an added effect)
 * End Hole
 * Death Colosso
 * Grave Night
 * Anti Spell (probably not with Mind Mines)

Spells ive considered

 * Arc Aura (for obvious reasons)
 * Enigma Aura (Good alternative to Repair)
 * Next Ready (In case your fighting a Sunspot Tama and havent used Exceed)
 * Repair (Personally wouldnt use cause its SUPER expensive)
 * Lost Technology (Trash 3 AW to crush 2 opposing LC)
 * Final Destruction
 * Three Out (Draw 2 cards then discard 1)
 * Inactivity  (Trash and get signi)
 * Strike Impact
 * Lives Gut 
 * Get Open (View cards and trash what you want)
 * Attraction (Find other spells)

I need help with choosing which Signi to run
I cannot decide which signi are good enough or even how many of each to run. There are ALOT of good signi but there are soo many options. Ancient Weapons and Devils are the best ones to run obviously but Ancient Weapons may be better but Devils do get power boosts for a specific amount in trash. Either way i need help creating this deck and i appreciate any help as its suprisingly difficult to make a Rainbow Ulith.

Thanks in advance!!
