I have three questions,
1. My oppenant attacks and i block with my Avacyn, Angel of Hope
he then gives the attacker Proection from White, is the block still legal or does it get through?
2. I attack with Vampire Nighthawk
, and he lets it through, i then activate Vizkopa Guildmage
, does he lose 2 life or 4?
3. If i have Multiple creatures with Extort, am i correct in assuming i have to pay for each one when i cast a spell?
