None of those were developped during a pandemic and had their expansion delayed by 5 months. Maybe some of the abilities do not have VFX good enough to show, or maybe they wouldn't make much sense to show in just a 30 seconds teaser.

All we can be fairly certain off is that the voidsent is used in oGCD and you seem to build up to the transformation. That's litteraly it.
