So I was playing my friend’s purrely deck and he got Expurrley Noir on t0
I happened to have the Sea Turtle Kaiju in my hand at the time so at the start of my turn I said I would tribute his purrley to summon kaiju on his side of the field. He claimed that he could activate the effect of one of his other purrley cards which would bring it back because his purrley was sent to the graveyard by my card effect. I claimed that my card effect didn’t sent it to the graveyard, my tribute of his card sent it there and he shouldn’t be able to activate his effect. I heard Kaiju was a fool-proof counter to purrley and I can’t find any good explanation of this online. Can somebody explain who was correct here?
The card he used was My Friend Purrley
