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.
No. It wouldn't make any sense to have a "Quick-Play Field Spell" for example.
No, there isn't. Unless you count a Field Spell Card, which is a spell card but has its own zone, so technically you can have 6 spells active.
You can set as many traps as you desire each turn, until you fill up the spell and trap card zone. You cannot have more than five traps on the field at once.
Polyester is more likely to trap heat and moisture rather than breathe.
No. it get it's 200 g's more than that bakugan's g's.
Mystical Space Typhoon is a Quick-play Spell that destroys 1 Spell or Trap card on the field. It's more useful than the Trap Dust Tornado, since you can use MST as soon as it's in your hand (assuming you have a S&T zone open).
Yes
The Citi Card does come in more colors than just blue. The color of the credit card depends on which card is chosen. For example they have a green Forward card and a black Diamond card.
yes, that is why the card has more than one spot for it
If you are selling a card, it is important for you to go to more than 1 shop.
because a bakugan trap can have more than one attribute (not at the same time)
basically its like a fight to the death last resort card. if u r at 1000 or less than u select one and only one monster on ur own side of the field and all the rest of ur cards r sent to the graveyard. after that, ur opponent will select a monster out of their own deck, (i dont think extra deck counts) and special summon it to their side of the field. then, the selected monster on their side of the field attacks. whichever monster wins the controller of that monster takes the game in the End phase
