Yugioh Questions...?

Question

=Can you or your opponent just sacrifice a monster with 4 stars for no reason other then to kill it because it he has no more space in the field or to get rid of your monster.

=Also, can one just destroy (get rid of) magic or trap cards on the field because one has no room for more and does not really want to activate the current magic/traps effects?

=Lastly which structure deck is the best one from the new ones?

Answer 1

to both of your questions no and the best deck would be dark empire deck

Answer 2

Rise of the Dragon Lords is the best.  It comes with Foolish Burial, Trade-In, and Morphing Jar.

As for the first two questions, you cannot send cards from your field to the graveyard unless a card allows you to or instructs you to.

Answer 3

First question anwser: no you your opponent can't just destroy a monster for no reason even if his spaces are full.Only when you tribute.

Second question anwser: no you can't do that either unless you have a mystical space typhoon to get rid of your own if you want

Third question anwser:Probably: Rise Of The Dragon Lords because that deck can summon high level monsters easily!!
