Forum:Six Samurai and Crystal Beasts

1)If I control 2 Six Samurai monsters and I activate the effect of one of them but the opponent negates it with Divine Wrath or Gladiator Beast War Chariot ,do I get to destroy another Six Samurai to protect it from being destroyed?

2)If one of the Crystal Beasts effect was negated by Divine Wrath or Gladiator Beast War Chariot,can I send it to the Spell/Trap card zone?

3)This might seem out of topic but can you activate the effect of Ancient City - Rainbow Ruins which negates Spell/Trap cards multiple times in the same chain?
