In the actual card game, Enchanted Javelin is a Normal Trap card. However in the game Duelist of the Roses, it is an Equip Spell card.
No.
Dust Tornado is a Normal Trap Card. It destroys one Spell or Trap Card on the field, then you can set 1 Spell or Trap Card.
It destroys one magic or trap card on the field. It is chainable. *NOTE* It does NOT negate the effect of a spell or trap card. It destroys one Spell or Trap card on the field. This Spell or Trap card does not have to be one of your opponent's ones; it can be any Spell or Trap card on the Field. It is clearly stated in the text at the bottom of the card. Destroys 1 magic (spell) or trap card on the field. Really now.....don't be lazy.
Yes, as long as the spell card is a Quickplay Spell, and the trap card is not a Counter Trap. So you cannot chain Monster Reborn to any trap. Nor can you chain Book of Moon to a Counter Trap, for example.
Yes.
No. If you selected a Set Spell Card, then Trap Master's effect is wasted - though at the least you may have gained an advantage by seeing the spell card.
Every Spell or Trap card can have only one icon. For examples, an Equip Spell can't be a Quick-play, and a Counter Trap can't be Continuous.
A Normal Trap card is any trap that does not have a symbol after Trap Card (an infinity symbol for Continuous Trap, an arrow for Counter Trap).Normal Traps are spell speed 2, and go to the graveyard after they resolve.
No, sending the card is a cost to activate the effect. So basically when the effect has been activated as chain link 1, the Spell/Trap card is no longer on the field and therefore can't be activated in chain.
There is a card called "A feather of the phoenix" that if you discard 1 card from your hand you can return a card from your graveyard to the top of your deck. So you can pick any card in your graveyard including a spell or trap card.
Yes. If a Continuous Spell or Trap card was already on the field, then Number 16 Shock Master does not stop you using the reusable activated effects of that card. The correct term for this is to 'activate the effect' of the spell or trap card, as opposed to 'activate a spell or trap card' which is when you flip them face-up or place them face-up on the field.
In general it means all effects, be it the resolving effect of a spell, trap or monster, or the reusable effect of a continuous spell or trap.
