Looks like you are Modern legal! Was it a Modern FNM?
Thoughtseize and
Inquisition of Kozilek are the best hand hate for your mana/life investment.
And I'll mention it just in case you haven't seen it, but
Faerie Macabre is pretty good graveyard hate, and you actually have the possibility to cast it as a creature if that is the stronger option at the time. Tormod's Crypt is also a fantastic card, so I'm not saying you made the wrong call! Just pointing out a card that you might have missed and can also attack your opponent's life total. :wink:
