Bug Report: Lunalight Crimson Fox vs Black Slash Dragon

[JediMasterDraco]

When Lunalight Crimson Fox activates it's effect to target and reduce a monster's attack to 0, Black Slash Dragon is unable to negate the effect. Note that Black Slash Dragon's effect states "target" and that is the only limitation. Please fix this because I have lost three games because of this bug.

Hi, Official TCG Judge here:

Does Red-Eyes Slash Dragon have a legal cost to negate? There needs to be a face up equip card on the field. Otherwise, please provide a replay of the bug occurring.

sometimes your oponent can prevent your negation activating someting else in response to his own crimson fox, in those cases you will miss the chance to negate the effect.
that was a way to bait slash dragon effect time ago when red-eyes was meta

That's not how it works. That only applies if the effects are simultaneous (see SEGOC).
You cannot chain to your own effect before your opponent has the opportunity to chain to it.

It's not a bug just couple of effects activating together.
Slash dragon cannot negate an effect unless it's a direct response. In your case opponent probably fusion summoned using 2 or more lunalight monsters, then those sent monsters activated their effect one after another. Crimson fox was not the last effect to activate in a chain so you couldn't negate it. Simple example: 1 and 2 activated, 1 targets you and 2 doing something else, you being 3 cannot chain to 1 directly.
