Actually, I asked that in the questions thread. I can invest the EVs and then let it evolve. Then, I use the corresponding berries to reduce the EVs. Then, I can teach it Sucker Punch.
Also, this wasn't difficult. I just didn't have what I needed because before I learned how to RNG, I had given away tyrogue, or I havent caught any pokemon. So I wasn't prepared, I didnt have what i needed to start this sooner. That's all, this isn't hard at all. The RNG process was too easy, just I didn't have the Pokemon, or whatever so it was all good. :)
By the way I'll leave Scizor at lv 10 with Pursuit + Superpower. Scyther doesn't learn it.. which I forgot. So you'll receive a level 10 Scizor with those moves, no EVs.
