Cool Card Design of the Day
Fatal Blow /
Crushing Pain effects are hard to do well, because they're removal spells that don't work on their own. Anything really worth casting a spell to kill that isn't already trumped by one of your creatures is probably killing the blocker you use to prime your spell, so you're often 2:1'ing yourself. If black-red had more 1/4s, that might help.
Anyhow, I found a really nice way to even out the card EV here.
