Magic the Gathering: Question on card 'Hissing Miasma'?

Question

Okay, my opponent has two 'Hissing Miasmas' in play. I am playing my sliver deck and attack with 3 slivers with double strike. How much life do I lose and why? First one to give answer with explanation gets the points. I will be checking back frequently today, I hope you can answer quickly. ;)

Answer 1

You'd take 6 damage.  Here's the breakdown:

1) You attack with 3 Slivers

2) One of the Hissing Miasmas activates once for each attacker.  Therefore, you lose three life.

2A) At the same time, the other Hissing Miasma activates.  You lose 3 more life.

3) Each of your Slivers is declared not blocked.  

4) Each Sliver hits for First Strike damage

5) Each Sliver hits for regular damage

Therefore, you lose 6 life.  (Double Strike activates during the combat phase, after attackers have been declared and Hissing Miasma activates)

Answer 2

You will lose a total of 6 life. Each miasma will trigger 3 times, since 3 creatures are attacking. Double strike doesn't mean that a creature attacks twice... it just deals damage twice.

Answer 3

hey... so your opponent has two 'Hissing Miasma'  in play. You're attacking with three creatures. 'Hissing Miasma' card text as follows:

'Whenever a creature attacks you, its controller loses 1 life.'

Its really quite simple... You lose 6 life. You attacked with three creatures and 'Hissing Miasma' will take away two life for each attacking creature you control because there are two 'Hissing Miasma' in play, whick are stackable, and regardless of your creature's double strike. Double Strike only means that your creatures will deal damage twice, not attacking twice. That's about it. Get your game on!
