Innistrad: Midnight Hunt
45/100
Loses value in 2HG: incremental lifegain.
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.
Choose up to three target cards in graveyards. The owners of those cards shuffle them into their libraries. You gain 2 life.

Fits the same colour identity — 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 Turn the Earth.
