Extort (Whenever you cast a spell, you may pay {W/B}. If you do, each opponent loses 1 life and you gain that much life.)
For example, i have three creatures with exort on my board, i cast a nother spell and pay the extra exort coast with one {B}.
Now there is the question:
Does it trigger on each crature ore just once? ... asked in an other way: Does each opponent loses three life or just one life?
My thoughts: I pay for Exort and not for a aktivated ability of a single creature. It feels like exort is kind of a pool, if it is payed eacht creature with exort triggers.
Help me plz.
Best regards!
EDIT: I found this creature:
Pontiff of Blight ... speratly by paying it or like my thoughts?
