There's a bit of confusion here between the terms 'negate' and 'destroy'. MST is a destruction card, it cannot negate the effect of an activated card. If Polymerization is activated, chaining a destruction card to it like MST won't do anything. Polymerization's card may go to the graveyard earlier than normal but the effect will still resolve. Likewise chaining a second MST will just destroy the first MST's card, but the first MST will still resolve, though as above there is no need to 'save' Polymerization since it's going to resolve properly anyway.
To stop Polymerization from resolving, you must use a negation card like Magic Jammer. That will stop the effect from ever happening.
Yes, if your opponent activates any Spell or Trap card, it can be chained to and countered with Dark Bribe, unless it is specifically forbidden.
Polymerization is a spell speed 1 card. You cannot activate it in your battle phase at all.
You have spelled it correctly: opponent.
"Light of the Living Arrow" is also known as "Spell Shattering Arrow".The actual (as opposed to the anime version) card effect states:Destroy all face-up Spell cards your opponent controls. For each destroyed Spell card, inflict 500 damage to your opponent.This card will only destroy face-up Spells and cannot be activated until your opponent has a face-up Spell card.However, since this is a Quick Play Spell card, if your opponent activates a Spell card you can chain to its effect with this card. When the chain resolves, your opponent's Spell will be destroyed, they will lose 500 Life Points, and then your opponent's Spell card's effect takes place.This card, like "Mystical Space Typhoon", cannot actually negate card effects. However, if this card is chaining to the effect of a Continuous Spell (i.e. Continuous, Equip, and Field Spell cards), when the chain resolves, that Spell card's effect disappears.
That is the correct spelling of the word "opponents".
Yes, spell shattering arrow does work when your opponent activates a normal spell in Yu-Gi-Oh. The shattering arrow spell destroys all face-up spell cards of your opponent.
lets say you activate darkwold lightning to destroy an opponent's spell/trap then your opponent chains with a spell/trap of their own, you now missed the timing and cant discard causing you to be stuck with a bunch of darkworld monsters in your hand..... for a clearer explanation, type the exact question at google
Yes, there can only be one active at any one time. If you already have a Field Spell active, you can replace it with another, the first is destroyed when you activate the second. If the opponent has one, then it is destroyed when you Field Spell card resolves. Field Spell cards can be set while another is active. Since the rule only affects active Field Spells, set cards are not destroyed by your opponent setting or activating a Field Spell card.
OPPONENTS...
No, you can't. You can only activate a Quick-play Spell on your opponent's turn if you have Set it on a previous turn.
Dark Horus has a Trigger effect that can be activated after an opponent's spell card resolves. However if that spell card's resolution destroys Dark Horus, or flips him face down or removes him from the field, then he is unable to trigger his effect. So Dark Hole will simply destroy him, and he won't do anything.
The spell Sadie Kane used to destroy the door in the Red Pyramid was ha-di. It is the Egyptian word for destroy.
