I disagree that we can apply the partial fix. The scenario says that the Smiter was put into the graveyard when Essence Scatter resolved. It should still have been on the stack at that point, with both players receiving priority before the Smiter resolves. In the “real world” (i.e., not as precise as the manual priority passes on MTGO), things happen a lot more simply and fluidly:
A: “Loxodon Smiter?”
N: “Essence Scatter.”
A: *bins Smiter*
As opposed to a more technically detailed sequence:
A: “Cast Smiter, pass priority.”
N: “Essence Scatter, pass priority.”
A: “Pass priority, Smiter is countered, move Smiter from Stack to Graveyard, pass priority.”
or
A: “Smiter can't be countered and remains on the stack. Pass priority. Smiter resolves. Move Smiter from Stack to Battlefield.”
However, let's look at why Angie was binning the Smiter: because she thought it was countered. She moved it from the stack to her graveyard. Essence Scatter should have just done nothing–the Smiter should have remained on the stack. It's not like the classic
Path to Exile example, where a card is supposed to go from the Battlefield to Exile, and goes from the Battlefield to Graveyard instead. Since the GRV occured when the Smiter wasn't supposed to be changing zones, I'd say the partial fix doesn't apply.
GRV to Angie, FTMGS to Nelson, and back up if it's not too complicated.
