Catastor and Damage Step

From Yugioh wikia.
Basic stuff, I learned.

During the Damage Step of the Battle Phase, the damage is calculated from the declared attack.

If the defending monster is face-down, it is flipped face-up first during this Phase.
A.O.J Catastor, Lightsworn Eileen~~ Mashimaro AKA mashmaloon~~

Another interesting stuff here:
If “Ally of Justice Catastor” or the opponent’s monster is face-down at the start of the Damage Step, the effect of “Ally of Justice Catastor” will not apply.
So, when battling with "Ally of Justice Catastor", "D.D. Warrior"'s effect will not activate, since he is destroyed before Damage Calculation (and "D.D. Warrior"'s effect activates after Damage Calculation)
The same goes to D.D. Warrior Lady, BUT if Catastor attacks a FACE DOWN warrior lady...
Hmmmm.......
If “Ally of Justice Catastor” or the opponent’s monster is face-down at the start of the Damage Step, the effect of “Ally of Justice Catastor” will not apply!!!!


If the defending monster has a Flip Effect, it is applied after Damage Calculation, but still within the Damage Step. The Flip Effect does not affect monsters that have already been destroyed as a result of Damage Calculation. This includes the monster itself, so a flipped "Penguin Soldier" that was destroyed in battle cannot select itself as a target since it has already been destroyed.

In the Damage Step, only certain cards and effects may be activated.

These include:

* Counter Trap Cards ("Solemn Judgment", "Dark Bribe").

* Normal Trap Cards, Continuous Trap Cards, and Quick-Play Spell Cards that alter the ATK and/or DEF of one or more monsters on the field ("Blast with Chain", "Rush Recklessly", "Castle Walls", "Reinforcements", "Shrink").

* Mandatory Trigger Effects ("King Tiger Wanghu").

* Flip Monster Effects (which are mandatory by nature) ("Cyber Jar").

* Some Quick Effect monster effects ("Kuriboh", "Horus the Black Flame Dragon LV8").

* Any card whose text specifically says it may be activated during the Damage Step ("Nutrient Z").

* Cards that do not meet the activation criteria, but whom Konami/UDE have stated may be activated in the Damage Step ("Null and Void").

Starlight Road is a no no~
Which monster's effect can be activated when being destroyed?
And its effect destroys all magic trap on the field?

OH!!!

I see.....
hmmm..
