If you were Wizard 20

[Rubik]

Sure. We could also copy each others spells.

I already plan on having all the spells. All of them. Except maybe some [vile] ones that have nothing but horrible uses. And I'm not sure if a wizard can copy from a level 1 ardent (with ML = HD) using the StP erudite minion/Psychic Chirurgery trick to learn them all.

So, what feats would everyone take?

I know I'd take Wedded to History, three levels of cleric and Initiate of Mystra, Supernatural Transformation (Psionics), and a lot of metapsionic and metamagic-adapted-to-psionics feats. Heck, I've already got a list of all the ways to abuse the Dark Chaos Feat Shuffle to get lots of feats. I'm having trouble filling in all the slots, in fact. More than 2,100. I could fill them in with Metamorphic Transfer and such, but there're only so many times you'll need to use a Supernatural Ability from a shapeshifted form in a day.
