probably gonna very useful when Espa Roba will come to duel world. He uses Jinzo so this can destroy it easily. Crowler's cards needs to attack to activate effect.
I'm pretty late to reply it, but it doesn't work agaist AG monsters because they don't negate any traps, they only prevent trap (and spell) cards to be activated. Preventing and negating are 2 different things, it's the most basic rule in ygo, if the names are different, so they aren't the same thing.
negating is making it's target lose it effect.
in AG case, it's prevent activation, mean you can't use it at all during their attack but anything use before they declare attacking will work just like it should be.
