Obviously, Life/Light's only strength is the quantum production ability of the Rustler/Leaf Dragon, so having one or more removed from play is devistating, and that's why I play Blessings, to make them harder to kill, or at least one of them (since I never play more than one at a time). The deck works pretty well agains the AI, as the Rustler is too small to warrent anything other than a Thunderstorm, but against a human opponent, if they're smart enough to kill the Rustlers ASAP then the deck is screwed. Many decks have vital weaknesses like this. =/
