Just wondering on triggering. IE {thrull parasite} & {pontiff of blight} are both out in play. Being the parasite already has extort, and the pontiff gives all creatures extort would the thrull get extort twice? Also would one mana active both cases of extort or would I have to pay for both abilities seperatly?
{Pontiff of Blight} states quite clearly that creatures can have multiple instances of extort.
Each extort trigger is separate.
You would pay {W} or {B} for each separate trigger of extort.
