60/100
Gains value in 2HG: combat fog / damage prevention.
You're defending against two attacking players out of one shared life pool. Fog effects buy a full team turn.
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.
Buyback—Sacrifice a land. (You may sacrifice a land in addition to any other costs as you cast this spell. If you do, put this card into your hand as it resolves.) Prevent all combat damage that would be dealt this turn.
Shares the "combat fog / damage prevention" 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 Constant Mists.
