Gains value in 2HG: hits each opponent, damage to each opponent.
There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.
Drain and burn that reads 'each opponent' comes off one shared 60-life total, so the printed number doubles.
Ratings start at a neutral 50 and are adjusted by rules derived from 2HG's structure — shared 60 life, shared turns, two opponents. They'll be recalibrated against real play rates once teams start submitting decklists.
Unholy Annex At the beginning of your end step, draw a card. If you control a Demon, each opponent loses 2 life and you gain 2 life. Otherwise, you lose 2 life. (You may cast either half. That door unlocks on the battlefield. As a sorcery, you may pay the mana cost of a locked door to unlock it.) // Ritual Chamber When you unlock this door, create a 6/6 black Demon creature token with flying. (You may cast either half. That door unlocks on the battlefield. As a sorcery, you may pay the mana cost of a locked door to unlock it.)
Shares the "hits each opponent" axis — good candidates for your teammate's deck.
