Minmax challenge: Building God

[SorO_Lost]

Spontaneous Domain + Silent Image as a domain spell + Shadowcraft Mage
or
Spontaneous Domain + Spell Domain

Those would be my choices.

Don't forget this Feat

Spontaneous Domains [General] (Complete Champion, p. 62)
You need not prepare your domain spells in advance.
Prerequisite: Ability to cast 3rd-level spells, access to two or more cleric domains,
Benefit: When preparing your spells for the day, you can leave your domain slots open. You can then choose, when the situation arises, to cast any of the domain spells you could normally have prepared for a given level. However, you are still limited to one domain spell per level per day.
Normal: Clerics must prepare their domain spells before casting.
