[[Bloodchief Ascension]]
In a two-headed giant game, suppose we attack the opposing giant with a 2/2 creature, dealing 2 damage to them. Bloodchief Ascension gets a counter at end of turn if "an opponent lost 2 or more life that turn". So, did any one of our opponents lose 2 life, or is the calculation for how much life was lost carried out according to the shared life total rules, which would mean each of our opponents lost 1 life, and no counter is added?
Zendikar FAQ doesn't say anything about this, but it does say that the card checks for life lost, not the total difference of life (so for example if a single opponent lost 2 life and then gained 4 the ability would still trigger). This makes me suspect that the ability does activate: the attacked opponent lost 2 life, but they came out of the shared life pool. Anyway, I'd like a definitive answer, backed by the rules.
