SolutionBlack filled star.

Each row and column has to contain each kind of pentagram.

Also: I think it is the diagonals? Similar to determinant rule application.

Black star seems inevitable. Otherwise it would be the only row with no black star. Also, it would complete the pattern of black star moving from 1st to 3rd position.

It also is a perfect fit for a sudoku style with every symbol appearing not only once per line, but also per column. And completes "3 of every kind of symbol".

This is so simple, it looks like the IQ test from the prison in the movie Idiocracy.

There are multiple potential ways of solving this, and I concluded early on that "nah, it can't be that simple". So I went through the ones I could think of just after waking up at the crack of noon.
Row sequence.
Column sequence.
Diagonal sequence (with wrapping).
They all came down to a simple XOR, so Black Star.
