Gains value in 2HG: hits each opponent.
There are two opponents in 2HG, so every 'each opponent' clause resolves twice against a single shared life total.
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.
This spell costs 
less to cast for each creature that died this turn.
Discard your hand, then draw eight cards. Blood for the Blood God! deals 8 damage to each opponent. Exile Blood for the Blood God!
