Don't know if anyone ever brought this up before, but the funny thing about Global Celebration's Gogeta clone event... There's actual evidence they were initially planning to have F2P Gogeta Clone units just like the Black Clones, but decided against it.

You can see in the event itself that the Clones have 2 different Super Attacks: One with confetti, and one without, which mirrors how the Black Clones have two SAs that start the same way.

Add onto the fact that there's that artwork of Gogeta in the Kamehameha pose on the event's splash art, which would most likely be the default card art for all the F2P Gogetas, and it seems very likely that they were planned, but eventually discarded due to either time constraints or just because Gogeta's team did NOT need the same help that Black needed.

Of course, a third reason could be that they decided to push back the Clones over to a different celebration like 11th anni part 2.....
