In my deck bag is a fun Scizor SF deck. But I run it at least with 3-3 Cherim's, 1-1 Vesiqueen, Turtwig-GL, Chatot, Sableye, Unown Q, Unown R's. 4-4 is somewhat asking for the Donk to you. Thus I found this article was interesting, but the speed of the competitive format makes this 4 basic deck like this not realistic. But given that this is a younger author creation, I think it is great. There are many of us who have never taken the time to published an article on the gym. As mentioned most decks can easily donk a 60 HP pokemon.
BTW. Everyone should realize that the best Scyther in the format is the JUNGLE reprint, PL-130. I went deep into my card boxes to pull out 3 of my old, and NOW legal Jungle Scyther, so cool playing a card that was printed over 12 years ago. Still free retreat, but 70 HP, and -30 resistence, but 2x weakness. All in all, give me the extra 10 HP. It's combination of attacks for a basic actual is about the same, because I run DCE and have T2 Donked with that Scyther.
