Unclear questions can be reopened once the unclear parts are clarified.
Your question has been asked twice (here and here), and both times been closed because it "needs details or clarity". The community feedback has been mostly unanimous in saying that the question is unclear. There are enough users here who don't understand your question, such that it had to be closed.
It can only be reopened once you clarify whatever issues are unclear to the site users. Those users are the ones who are expected to write answers. If you don't clarify the confusing parts, then it would remain unclear.
Usually it's expected that querents edit their own question so it can be reopened. Alternatively, you can instead leave clarifications in comments (or here in this meta question) and other site users can edit the question for you. And once it's edited to be clearer, then it can be reopened.
Based on what you've said so far, here is an example of what your question could be:
I want to build a character with every spell that summons creatures, without using Wish or magic items.
This includes all conjuration spells that summon creatures, and all necromancy spells that make undead creatures.
They don't need to summon everything simultaneously, so if a wizard had these spells in their spellbook, then it would qualify.
Every summoned creature needs to have a stat block, so this does not include spells like Faithful Hound.
No Unearthed Arcana.
What character (class levels, background, etc) do I need to do this? I want to achieve this with the fewest total levels, with multiclassing if necessary.
Is that similar to what you are asking? If not, please clarify what you are trying to ask.
