Mound of The Bound Creator vs Kaiju

[tidal token]

So what if had Supreme King Z-ARC on the field and mound of the bound creator.
Could a kaiju card get rid of it, or does the tribute count as a targetting effect?

[paper pilot]

Tributing with a kaiju does not count as targeting or destruction

Also Zarc was already protected from targeting and destruction effects on its own, using mound is redundant
