Target player loses life equal to the power of target creature in the graveyard that died this turn is better than Target player loses life equal to the power of target creature that died this turn because it clarifies you cannot use it from a previous state, where it may have had counters or something. I decided on using power rather than toughness here, as it's a bit more black than toughness is green. i'd like to at some point design a green or blue or white toughness-matters card. would be fun
