Curse of Vitality

Mixed in 2HG — hits each opponent, but incremental lifegain.

• +22
  Hits each opponent

  There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.

• −5
  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.
