Creature — Horror
Alchemy: Murders at Karlov Manor
98/100
Gains value in 2HG: hits each opponent, team-wide edict, damage to each opponent.
There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.
Forcing both opponents to sacrifice strips two boards for one card — the classic 2HG blowout.
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.
When Lurking Spinecrawler enters, you may choose a nonland card in your hand. If you do, that card perpetually incorporates 
and gains "When you cast this spell, each opponent sacrifices a creature. Each opponent who can't discards a card."
Whenever you cast a multicolored spell, for each of that spell's colors, each opponent loses 1 life and you gain 1 life.
Shares the "hits each opponent" axis — good candidates for your teammate's deck.
Suggestions are characteristic-based for now. Once teams submit pairings, this becomes a real co-occurrence score: played in X% of teams whose partner deck runs Lurking Spinecrawler.
