I chose to go with Beguiler since even though it and Factotum have a couple overlapping abilities, you only need Int, and several of their abilities mesh together really well. The Factotum gets up to level 16 abilities, so you don't miss out on Improved Cunning Defense. The basic progression looks like:

Factotum//Beguiler
Factotum//Beguiler
Factotum//Beguiler
Factotum//Beguiler
Factotum//Beguiler
Factotum//Beguiler
Rainbow Serpent//Beguiler
Rainbow Serpent//Factotum
Rainbow Serpent//Factotum
Rainbow Serpent//Beguiler
Rainbow Serpent//Factotum
Rainbow Serpent//Factotum
Rainbow Serpent//Beguiler
Rainbow Serpent//Factotum
Rainbow Serpent//Factotum
Rainbow Serpent//Beguiler
Beguiler//Factotum
Beguiler//Factotum
Beguiler//Factotum
Beguiler//Factotum
Other than this appearing to involve brightly multicolored Lepidosauria, this build is brilliant.
