I've been trying it in Gold as well - it's quite funny!
To address the damage issue, I replaced some of the Eternities with Golden Nymphs - this also freed up some slots from Animate Weapons, and reduced the necessity of comboing Animate Weapon + Eternity. To address potential deck-out issues, I added one Mitosis (which also makes for funny situations). This gives the deck some more flexibility, but it sadly still is really sad against Electrocutor/Lobotomizer, Gravity Shield, etc... And do NOT let an Eternity get stolen by a rainbow deck! :O
EDIT: Here's what I've been trying. Also I realize that Golden Nymphs aren't exactly common... oops.
