Fair point, looking back and taking your criticism into consideration, I have a new rating for this piece:

Creativity: 4.5/5 - I stand on the allyswap being able to be good defense, but the element that vro mentioned above was something I never thought of, which makes this a much better ability for the theme of a Shinobi, as you can swap with a forking unit like Knight or Ninja and make very strong trades.
Theme: 2/5 - I stand by my rating, as having a decoy is interesting, but Shinobi is a far superior theme for this unit.
Execution: 4/5 - Whilst looking at the double move still throws me off a bit, looking at it more makes it fairly colorbound when it tries to move forward, and if it turns out to be a promoting minion it can still promote, so it works for what looks to be a very offensive moveset even with the allyswap. However, it will get stuck if it has no ally to swap to so you have to have something nearby it to make proper use of it. Also, perhaps explaining whether this should be a promote or not could help with the design of the moveset a bit?
