Black Widow - Tsarina
When Black Widow attacks, she deals 2 damage to your opponent. Your opponent can prevent this by spinning one of his characters down one level.
Marvel Girl - Humanity
When you are attacked, you may spin up Marvel girl one level. If you do, gain 2 life.
Example 1: I have a level 2 Marvel Girl and my opponent attacks with Black Widow, I spin down Marvel Girl to level 1, then spin her up to level 2 and gain two life. This is no problem.
Example 2: I only have a level 1 Marvel Girl fielded when my opponent attacks with Black Widow, can I trigger Marvel Girls effect first. i.e. I spin up Marvel Girl to level 2 and gain two life, then spin her down to level 1.
Example 3: (Let's assume example 2 is incorrect and I am now allowed to trigger Marvel Girls effect first)
I only have a level 1 Marvel Girl fielded when my opponent attacks with two Black Widows. I can't spin Marvel Girl down so I take 2 damage. I then trigger Marvel Girls effect between the attack of the first and second black widow. Spinning Marvel Girl up to Level 2 and gaining 2 life. The effect of the second attacking Black Widow then triggers so I spin my Marvel Girl down to level 1 again to avoid taking damage.
