@snowydude good luck with the testing. I think the "what if they force it" concept is a bad one (in general). They can force EVERYTHING - that's not a reason not to play a card. What if they force EE or Abyss? Does that make them bad cards? No. Also, you realize both damnation AND abyss are 4cc sorcery-speed spells, yes? Both leave you tapped out on your turn. 3-4 abyss may be excessive depending on your meta. 1-2...especially if your leaning toward 1...is basically saying it's a silver bullet you don't plan on casting until a few turns in when you can tutor for it, or you're hoping for christmasland where you draw your 1-of and 4 mana on turn 1. If you're not planning on casting it until turn 3 or 4, damnation does just as well with less dead matchups. Abyss is a great card, i love it...but it has its drawbacks. if you really want to use abyss to fight aggro, you need no less than 3 unless you are chock full of tutors.
