Not really: you can only get 1 each. Dinosaur Kingdom works because you have a whopping total of 6 1900-ATK monsters (3 each). And if 3 1900-ATK monsters are enough for you, go with Harpies' Hunting Ground instead: 3x Sonic Duck is very easy to get, and you get S/T destruction with the Harpies on top of that.
Wrong. A continuous spell is strictly continuous spells (cards with the infinite sign). A field spell is...well, a field spell. A field spell does have a continuous effect but that's it. It's all on the words.
did anyone else notice this it seem when your opponent have this card you can click on it and active it effect because when i was dueling someone he summon this and i did this and that cost him the duel
