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.
'Each opponent discards' is a two-for-one in 2HG. Syphon Mind and friends jump several tiers here.
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.
Each opponent discards a card. You create a 1/1 black and green Pest creature token with "Whenever this token attacks, you gain 1 life."
