Here's a variant on one of my favorite builds:

Beguiler 1 (Versatiles Spellcaster & any metamagic)
DFA 1
Binder 1 (Improved Binding)
Anima Mage 7

Lets you bind 2 5th level vestiges (my favorite combo being the the two 5th level vestiges that give you gaze attacks, because 1 gives you nice bonuses & a reroll every 5 rounds, and having two gaze attacks is just mean). Also gives you 2 least and 2 lesser invocations.
