Puzzle #1:
1) Zamiel clues number 2's to Andrey as a 2 Save.
2) Cory clues number 3's to garbo as a Finesse + Prompt.
3) Andrey clues reds to Cory as a Stacked Finesse.

Once interesting thing about this line is that it breaks the "rule" of the 2 Saves Convention, as listed here:

However, in this case, Andrey is able to reason that Zamiel might have wanted to break this rule to allow the two Finesses to happen, which would be very efficient. So he should be wary that his 2 may be blue 2 in this particular circumstance.
