Prestige Class spell progression

[Shadeworld]

I'm sure this question has been asked before, and I'm sorry but I couldn't find any further reference.
Here I go.

Should I take 3 levels of Illusionist, then 3 levels of Cleric, one level of Mystic Theurge and then level the rest of the way as Veiled Illusionist, could I chose Mystic Theurge as the "+1 Existing spell casting class" spell progression. Thus advancing both my Arcane and Divine spellcasting abilities?

1) what is the Illusionist?
2)you can't chose MT as the +1 spellcasting class. since it's not, it just increases other spellcasting classes.

1) Illusionist, was thinking the school specialization of the Wizard. Force of habit to write it as the base class.

2) How is it not? I mean, where does it say that?

it doesn't gain casting of it's own. it increases other classes casting. That's why it's not a casting class. No spell list for it. no spells per day. Nothing that makes a class a casting class.

Shadeworld has it right. The MT does not have it's own spellcasting, it just increases the spell progression of other classes. It says so right in the class description.

Spells per Day: When a new mystic theurge level is gained, the character gains new spells per day as if he had also gained a level in any one arcane spellcasting class he belonged to before he added the prestige class and any one divine spellcasting class he belonged to previously.

Evangelist could probably advance MT, but no other prestige class can do so.
