A: To review…
Perform a “Miracle” says:
Discard one Artifact that is face-up in front of you. Then, setting your hand aside, draw two cards, play one and discard one. Make that draw three, play two, discard one, if your Artifact was one of these [either Biblical or Future Wisdom cards].
Fast Forward says:
Immediately draw two more cards, put them in your hand, and play two cards.
The draws and plays provided by the Fast Forward should definitely interact with your main hand, not the Miracle mini-hand. There is still a question of the order of operations, and, after some discussion with Andy, the call is that when you play the Fast Forward out of your Miracle hand, you draw two cards into your main set-aside hand, finish your Miracle, then pick up your main hand and make the two plays from the Fast Forward.
