Greater Good - Commander: Marvel Super Heroes (Rare) [MSC-174]

Greater Good is a four-mana enchantment from Marvel Super Heroes Commander that lets you sacrifice a creature to draw cards equal to its power, then discard three. It rewards building around big-power creatures that are easy to replace, since sacrificing a six-power creature nets you three extra cards after the discard. Mono-green decks running token generators or reanimation can keep feeding bodies into this engine, turning excess creatures into fresh cards. The downside is the mandatory three-card discard, so it works best when you have graveyard synergies or a way to dump cards you don't need.
