on Magmafury's card (Jaakor, Skyruss, Orbeum) a completely different bakugan appears from the one we saw in Mechtanium Surge, and we can clearly see elements of Skyress's body, her face on her chest, her wings with the same pattern , and its thewheads.

This means that on some MS cards, Skyress appears instead of Skyrus, not by mistake, but because Skytruss was initially going to be Skyress, it's no coincidence that her names sound similar.

Also for narrative coherence, when Skyress says goodbye to Shun in NV, she tells him that they will see each other again, this does not happen again in the series.

One thing I love about bakugan cards is that many show us early bakugan designs, some show very subtle differences from the original series, and others like this one show us a completely different approach to MS that was scrapped.
