As someone who also sucks at skill moves, just learn like 2 or 3 moves and you'll be fine. Learn both fakes (pass and shot), berba spins and use some stepovers too. Just know when to effectively use them. For me, 9/10x if I spin and fake shot in the box, I'll draw a pen
Yeah the few skill moves I use are pretty much restricted to ball rolls, fake shots and the occasional berba spin or heel flick. Tbh the ball roll helps me out the most.
