Swords of Revealing light is not a card that targets, so Spirit Reaper will absolutely not be destroyed by it, even if it is face up.
While face-down, Spirit Reaper can be targeted, and it will not be destroyed.
Both Spirit Reaper and Gorz trigger from the same thing, and will form a chain with each other. As the turn player's mandatory effect, after battle damage is dealt, Spirit Reaper's trigger will be chain link 1. Gorz will go on the chain as chain link 2. Gorz's effect will resolve first and summon him to the field, then Spirit Reaper's effect will resolve and the opponent will discard a card if he has any left. Lastly Gorz's second trigger will start a new chain, to summon the token.
Depends what you mean by 'work' - work properly or work to destroy it? Spirit Reaper is only destroyed after the targeting effect resolves, and if Spirit Reaper is still face-up on the field. After Interdimensional Matter Transporter resolves, Spirit Reaper will be in the removed from play zone. So Spirit Reaper will not be destroyed, even when returned to play.
Yes, "Torrential Tribute" will destroy "Spirit Reaper". The effect of "Spirit Reaper" states that it cannot be destroyed in battle. "Torrential Tribute" destroys all monsters on the field and has nothing to do with battle.
Hyper hammerheads effect has to resolve before spirit reapers effect would destroy itself. So spirit reaper will be returned to your hand by hammerheads effect and your reaper will not be destroyed.
spirit Reaper
nope only super rare
Both of Enemy Controller's effects target, so Spirit Reaper will die after it resolves. Book of Moon targets, but Spirit Reaper doesn't destroy itself until after the targeting effect resolves. However in this case, it will now be face down, and its self destruction effect will not apply.
as long as its a random, clear way of choosing a card... it can be done that way. example: you choose the card example two: your opponent shuffles the cards in their hand, not (into the deck) (without looking).. and they pick a card... the text never states who picks it so you can use either one of these examples i used the text of the "spirit reaper" card i have #PGD-026
Assuming both monsters survive the first attack, yes, Cyber Twin Dragon can declare its second attack against the same monster. So if the opponent had an attack position Spirit Reaper, you could attack it twice. It would not die, but the opponent would take battle damage to his lifepoints twice.
The monster who battles with the monster equipped with Rainbow Veil, has its effect negated. So if a monster equipped with Rainbow Veil battles a Spirit Reaper, Spirit Reaper's continuous effect will be negated, it can be destroyed by battle.
No, BESD's effect works just for him.
