Yes. All the monsters are summoned at the same time, by a single resolution. Torrential Tribute can be used in response to this.
geminis must be summoned a second time to get the effect while effect monsters only need one summon
Yeah. There's just two kinds of monsters you need to look out for; 1 - Monsters that say "Can only be special summoned by..." These monsters have to be summoned properly by their own effects first, if you wish to use Monster Reborn on them. You can't just discard them and use Monster Reborn. 2 - Monsters that say "Cannot be special summoned except by.." The only way (barring a few highly specialised circumstances) these can ever reach the field, is by following their own text. They cannot be special summoned from the graveyard by Monster Reborn, even if they were properly summoned first.
Gemini Monsters Are monsters that can be summoned in the normal way. However Class as Normal Monsters, until they are normal summoned (Twice, if the Gemini Monster was originally Normal Summoned) Where you will get an effect. This does take up your normal summon of the duel, so in other words, you will have to rely on Special Summoning other monsters OR If you have normal Summoned a Gemini Monster, you will have to wait a turn (unless you use Double Summon, or Ultimate Offering) until you can use the effect There are some cards that allow you to Special summon a Gemini WITH it's effect (i.e. Supervise). Hope This Helps
Monsters who can only reach the field by special summon (including Ritual Monsters) can only be special summoned from the graveyard if they were properly summoned initially. If Black Luster Soldier is simply discarded, or was used as a fusion component from hand, then he can't be special summoned by cards like Monster Reborn or De-Fusion.
The first turn of the game? No. The first turn they are summoned? Yes, of course.
Yes, you can activate Torrential Tribute whenever a monster is summoned. Here's a hint you can also activate on your turn to destroy your opponents monsters.
As long as he is not being summoned in the Damage Step, then yes, you can. After he is summoned, his triggered effect activates. You will chain Torrential Tribute to this.
Yes, but not always. Remember there is only a limited amount of cards that can be activated during the Damage Step of the battle phase, and Torrential Tribute is not one of them. You cannot use Torrential Tribute in the damage step, and that is where Gorz is special summoned if you trigger him from battle damage (his token is summoned in the damage step too). However if you trigger him from effect damage and summon him, Torrential Tribute can be used in response - unless you take the effect damage during the damage step, in which case the above still applies.
the chaos lord i think
Yes. Ra's only protective effect is that when he is summoned, no effects apart from his own, can be used in response. So cards like Torrential Tribute cannot be used against him when he is summoned.
There is a different person every time.
Triggers will always go on the chain first before any manually activated cards like Torrential Tribute. Black Rose Dragon's trigger will be chain link 1, Torrential Tribute will be chain link 2, so Torrential Tribute will resolve first, then Black Rose Dragon's effect.
The culprit change every single time
As it's effect mentions chaos sorcerer cannot be normal summoned or set.It can only be special summoned by removing from play one light and one dark attribute monsters.
Destiny Hero Dogma cannot be special summoned, except from in hand, by tributing three monsters. As an 'except by' monster, that means the listed method is the only way he can ever be summoned. He cannot be summoned by any other means, even if he was properly summoned first and then went to the graveyard.
