2HG Rating
84/100
Gains value in 2HG: hits each opponent, team-wide edict.
- +22Hits each opponent
There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.
- +12Team-wide edict
Forcing both opponents to sacrifice strips two boards for one card — the classic 2HG blowout.
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.
