Utopia's effect vs mirror force or any card that negates and destroys monsters

Hi I'm new here, I've recently come across this idea that Utopia's effect says it can negate an attack of any monster. Can I use Utopia's effect to negate my monster's attack when mirror force is played?

Example:I declare an attack on my oppnent's Vorse raider with Utopia or Great Shogun Shien.
Opponent responds with mirror force.
Utopia's effect chains my attack, removing an overlay unit to negate attack.
Mirror Force's effect is not resolved because I negated my own attack?

Utopia can't avoid mirror force. This question has been asked many times and you could've gotten the answer in 1 - 2 minutes with google.

It's been an official ruling since the start. You can't use his effect when that happens. Mirror force, d prison etc will work

As the turn player, during the Battle Phase you retain priority to activate Utopia's effect prior to your opponent activating any trap cards on their side of the field. Once priority has passed to the opponent (you declared an attack and didn't negate it), they can activate their trap cards and you're not able to respond with Utopia's effect anymore. At least that's how I see it.

It's more because Utopia is a Spell Speed 1 Trigger Effect and, as such, cannot chain to Spell Speed 2 effects. The only time it would go in a chain would be if there was another trigger effect that activated when a monster declared an attack.

Yeah, you are right. But basically what one should remember is that the only time when Utopia's effect can be activated to negate the turn player's attack is before the opponent responds with any of their trap cards.

Even then it won't matter because chains resolve backward.

Its spell speed 1. I thought it was spell speed 2 since it can be used not only in the battle phase but on your opponents turn.

It's been ruled a trigger effect with the trigger "When a monster attacks", and no trigger effects are Spell Speed 1, only quick effects.

What? Big mistake here, I demand that it must be fixed at once.
