Official Rulings
My battleline consists of three cards: Lollop the Titanic (AOA 014), Knoxx (AOA 326), and Mushroom Man (COTA 362). Lollop has 11 power, Knoxx has 2 neighbors so has 9 power, and I have no keys forged, so Mushroom Man has 8 power. Can I choose Brobnar and play Might Makes Right (AOA 043) to sacrifice these three creatures with a total of 28 power to forge a key for free, or will the power levels change as I start sacrificing creatures?
You will forge a key at no cost. When resolving Might Makes Right, you select all of the creatures to be sacrificed, and tag them for destruction. The rules for Leaves Play state that if cards leave play while resolving an ability, the instructions later in that ability refer to the cards as they left play. So, if you chose creatures with a total power of 25 and those creatures were successfully destroyed, you will forge a key.
