Please suggest me a caster build

Hello,

can you guys please recommend me a build for 0.4?
The last seasons i played Spark Stormweaver and LA Deadeye - this time i want to try something different - but once again a caster.
I plan to do all content and would eventually like to see some "pinnacle melting".

Currently i am drawn to Infernalist Witch Demon Mommy or maybe something as Ritualist.
Do you have any other suggestions that are fun? Thanks
