All your attackers have to be declared at the same time, before a response is made, and before the opponent declares blockers. You are not forced to make all your monsters attack, but any that you don't declare, have missed their chance to attack that turn.
If you are asking, do you have to declare all attackers together at the same time, then yes. There is a 'declare attachers' step in the battle phase, you have to declare all your attackers here, at the same time, before anything else can happen.
If you are asking, do all your creatures have to attack, if you want to attack, then no. You just declare the ones you want to attack with.
You "tap" (turn it sideways) a creature that isn't affected by summoning sickness during your attack phase to declare it as an attacker. Once all your attackers are declared, the defending player may assign blockers to them, then combat resolves and damage is dealt out simultaneously.
Yea, Magic: The Gathering all the way.
You have to keep two things in mind. 1 - Normally, you only get one Combat Phase, 2 - All monsters attack at the same time. Untapping a monster after it has attacked will in no way allow it to attack once more, because you are past your Combat Phase. Even if you were still in the Combat Phase, all attacks are declared simultaneously, and you are past the 'declare attackers' step.
I would suggest that you go to the magic the gathering website and look up their gatherer function. There, you can look up all the blue and black elementals in magic history and finc the set that has the largest portion of them. Hope that helps.
No, you would have to very unlucky, or very lucky to do that.
