In four submissions you managed to do these things:
Pinkie's "forever!" becomes "ruse!" (I love imagining her saying them in a similar way.)
Twilight is has become more confused by Pinkie than the Pinkie Keen episode
Create well detailed facial expressions of both Pinkie and Twilight
Use a running gag of the decoys with good timing (near the end of the comic)
Using the black suits and the flirting Twilight scene was a great idea
You've expanded the range of Pinkie's powers from just 4th wall breaking to something unexpected
You've inspired me to get back to work on my own project.
