ELI5 These Dark Matter Batch Drops of Players, Please

What’s the pattern/template to these? A player has an Endgame (or two) drop, plus multiple Invincibles, plus a MyTeam Anniversary, plus any prior 99 OVR being re-released, and/or some added?

And they’re not all the same? Is it…

Endgame > Invincible > MyTeam Anniversary > Other

And also on top of the variation of team/uni and ratings/badging, there is also positional variation?
