It can, unless it's the Damage Step.
There is only a limited amount of things that can be activated in the Damage Step, usually:
1 - Cards that modify ATK or DEF (Reinforcements, Shrink),
2 - Counter Traps,
3 - Any card that specifically says it can be activated there.
Fiendish Chain isn't any of the above so can't be used in the Damage Step.
Yes. It is like Spellbinding Circle. If a monster declares an attack, and something is used on it that makes it so the monster 'can't attack', then the attack stops. They don't just mean that the monster can't declare attacks, they also mean it can never be in a state of attacking.
Your opponent will be able to destroy one of your Crystal Beast Amber Mammoths in battle even if two or more are on the field. If you redirect a attack to an Amber Mammoth, the conditions to activate another Amber Mammoth's effect would be gone because your opponent finished declaring an attack against a Crystal Beast Monster you control.
Yes.
No, it is an Ignition Effect and can only be used in your turn.
Put the cursor over your Speed World 2 that's in your field spell zone then press Activate. Then you can deal 800 damage to your opponent by showing a speed spell in your hand and removing 4 speed counters. If you do the same but remove 7 then you can draw one card, and if you want, remove 10 and destroy a card on the field. Some Speed Spells need you to remove speed counters to activate.
The yugioh card "toon world" does nothing unless you have toon monster cards.Toon world is required for you to activate them and put them into play.

Yes.
After you activate "Heart of the Underdog", you draw a card from your deck like you normally would during your Draw Phase. If that monster you draw happens to be a Normal Monster, you can activate "Heart of the Underdog". You show the Normal Monster to your opponent as proof and draw another card from your deck. If that new card that you draw is a Normal Monster too, you can activate "Heart of the Underdog" again. You repeat the process until you don't draw another Normal Monster.
No, it is an Ignition Effect and can only be used in your turn.
Yes, Seto Kaiba is available as an opponent in the Fourth Level, after the Rare Hunters.
The following monsters inflict damage to your opponent when destroyed. Some of these effects will depend on whether you or your opponent destroyed it and/or if it was destroyed in battle or by a card effect:AbakiEarthbound Immortal Aslla piscuBalloon LizardMecha-Dog MarronOxygeddon
