Simple Tranquility

At the beginning of your upkeep, if you have drawn a card this turn, reveal the top X cards of your library, where X is the number of times a creature under your control was tapped or untapped during the previous turn, exile any number of enchantments among them, put any number of instants in the graveyard, and any number of artifacts/creatures on the battlefield, then draw cards equal to the number of enchantments exiled this way. Target opponent dies.
