Wacko you should read the other comments before asking repeated questions, the admins are doing a brilliant job but they shouldnt have to repeat themselves so often, you can use any deck for the poison and + life missions. but bear in mind, Jungo and freakz wont be much use when going against Nightmare.
Backslash is a ability that removes some of YOUR life points when u win,for the mission you'll need to remove life points from your enemy,soo I think that backslash doesen't count as removing life points.
You can use any card from any clan that does poison damage.
If you are among the first 200 ranked in one mission you will get the card free.Also you have a chance of getting on lottery.To enter a lottery for one mission u need to have 10 points minimum in it(if it's wins you'll need 10 wins , if its poison damage you'll need 10 poison damages) and you need to have bought credits at least 31 days before the missions ended.
