Option 1: Archivist 3/Binder 1/Anima Mage 10/Tenebrous Apostate 5/Tainted Sorcerer 1. Bind Naberius and Zceryl. You'll need Improved Binding, Dmm: Persistant Spell, and, well, whatever other metamagics sound fun. Take Con damage to power your metamagics, and then heal it rapidly with Naberius or instantly via summoned minions that can cast Heal. Persist all the spells you want. Also, your effective casting stat should be at least in the 50s due to the way Tainted Sorcerer works. Destroy everything in your path.
Option 2: By RAW, the Factotum's Cunning Brilliance could let you copy the spellcasting ability of a Sorcerer, Beguiler, Warmage, Favoured Soul, or Dread Necromancer as needed. This can lead to all kinds of wackiness.
