Gem-Knight Citrine VS Sangan

I've seen this come up a few times and I'm curious as to what the ruling should be.

Gem-Knight Citrine's effect states "If this card battles, your opponent cannot activate the effects of Spell, Trap, or Effect Monsters until the end of the Damage Step."

The issue I see is the timing for "until the end of the Damage Step." Does this mean when the whole Damage Step is competely over or does it mean at the SubStep 7 part of the Battle Phase called "End of the Damage Step" as posted here: http://forum.duelingnetwork.com/t2754-ruling-faq-clearing-up-the-most-confusable-rulings#bp?

If it's the former then Sangan's effect would not activate. But if Citrine's effect only applies until Substep 7 then I believe Sangan's effect should be activated.

I looked on the wiki but there's no actual ruling for Citrine. Only Tips. So I'd like to hear what the mods here will rule it as.

Thanks in advance

@Does this mean when the whole Damage Step is competely over-
yes

@If it's the former then Sangan's effect would not activate.
This is correct.

Nope Sangan and anything of sort will not activate in this case.

Condition
- Citrine on field
- Sangan set mode on field
- enter Battle Phase. Citrine attack Sangan (decleare attack)
- Sangan flipped
- enter damage Step Citrine (ATK 2200), Sangan (DEF 600)
- enter damage calculation (2200-600)
- damage calculation end, damage step end, sangan destroyed and sent to grave

So, Sangan effect activated.

Sangan active with same timing as mytic tomatoes (destroyed, send to grave, and active) Its happen During damage step
and citrine eff do states "If this card battles, your opponent cannot activate the effects of Spell, Trap, or Effect Monsters until the end of the Damage Step."

The question should arise is... can citrine attack got negated ?
Someone else has questioning if battle =/= declaring attack (not yet battling)

Declaring an attack is the 1st step for Citrine's effect to apply.

No the attack can't be negated.
Anything that activates when destroyed by battle is negated.
Everything that activates as result of being flipped face up is negated.
Anything that activates as result of an attack declaration is negated.
Anything that activates when sent to grave is negated.

Thanks for the responses. I'm assuming that Badass_Bunny is correct unless there's a ruling that says otherwise. May I ask why RareHunter's explanation is not correct just so that I can understand the process of how it all happens.

That way if it comes up again I will be able to explain why the "until the end of the Damage Step" part of Citrine's effect does not refer to the SubStep 7 part called "End of Damage Step."

Again, thank you for clearing this up for me

sangan's effect activates during the damage step, just like a mystic tomato would.

Citrine forbids all effects from activating during the damage step.

so naturally sangan will not activate as citrine forbids it.

No all cards that say "Until The End Of Damage Step" refer to all 7 substeps of damage step, including the last 7th step.

Oh okay, thank you
