Legendary Creature — HorrorForgotten Realms Commander
67/100
Mixed in 2HG — hits each opponent, but incremental lifegain.
There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.
60 shared life is a bigger pool than 20, so small lifegain is proportionally weaker — and it's the same pool your teammate is spending.
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 Nihiloor enters, for each opponent, tap up to one untapped creature you control. When you do, gain control of target creature that player controls with power less than or equal to the tapped creature's power for as long as you control Nihiloor. Whenever you attack with a creature an opponent owns, you gain 2 life and that player loses 2 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 Nihiloor.
