Was thinking about what kinds of cards might be in a Prophecies of Christ set (and mulling over 400 Years of Silence) and came up with this. Almost went with "Waiting on the Lord" and made it only good, but I think it's a bit more interesting this way. (Both sides are meant to be TC, just can't do that in the current card builder I'm using).
Can go on your characters early game to slow them down a bit but turn them into powerhouses for the remainder, or onto your opponent's later to (hopefully) stop them up until you can secure a win. Only one per deck, even in T2, and it sticks, so musicians can't abuse it too much unless the characters it's on keep dying. Green and white because it's somewhat prophetic and white already has similar effects (despite it making sense for this because it's from a Psalm).
