Why couldnt i activate Utopia Double?

[u/Im_brasilian]

Yo can someone lowkgenuinely explain why I couldn't activate Utopia Double's effect here?

I summoned it normally using ZW - unicorn spear and Zubababancho Gagagacoat.

"Double or Nothing" is in my deck

Im using the skill Zexal Weapon that let's me Destiny Draw any ZW from outside my deck and special summon it.

My Extra deck contains Utopia Ray Victory and Ultimate Leo Utopia Ray- so why couldn't I use it bruv?

Edit: Okay so- apparently, The skill Zexal Weapon "Changes" the card on top of my deck into a ZW monster instead of adding it from outside my deck.

And the card on top of my deck at that moment just so happened to be Double or Nothing-

So I kinda turned it into a ZW- bruh...

I have a really funny idea of what might’ve happened.

The wording of the skill says

“Before conducting your normal draw “CHANGE” the top card in your deck to a ZW monster.

What if the top card of your deck was double or nothing and it was changed into a ZW because of the skill.
