Photon Streak Bouncer vs gorz, trago, battle fader

Can photon streak bouncer negate these cards when their effects activate?

I believe it's card text is similar to LADD, as they both negate effects but do not destroy the card.

Quoting from wikia,

Quote :

"Light and Darkness Dragon" will also negate the effect of a monster which activates in the hand. The monster will not be sent to the Graveyard.

Therefore the opponent reveals Gorz, Trag or Fader to activate their effects, but they're negated. Opponent takes 1000 damage, but keeps Gorz, Trag or Fader in hand, and may special activate it again if you attack with another monster.

Nothing is confirmed yet though, just using LaDD as a reference.

ok tyvm

Photon Streak Bouncer's Effect: "Once per turn, when a monster your opponent CONTROLS activates its effect: You can detach 1 Xyz Material from this card; negate that effect, and inflict 1000 damage to your opponent."

Like u mentioned, those above cards were activated from HAND while photon streak bouncer can only negate monsters' effect on the field (I believe?).

レベル６モンスター×２
相手フィールド上で効果モンスターの効果が発動した時、このカードのエクシーズ素材を１つ取り除いて発動できる。その効果を無効にし、相手ライフに１０００ポイントダメージを与える。この効果は１ターンに１度しか使用できない。

Bolded part = Effect that activate on the field

So no it does not prevent gorz/Trago from appearing on the field. But you can negate the effect of it summoning a token. It will not negate the attack/defend change of trago since it is a continuous effect.

It also doesn't negate Fader as the effect of summoning it and ending the battle phase is together.

oh i see. ok thanks guys
