So basically, I just have to hope that the game gives me a shacking spot during my frame advancements? And as soon as I'm on my frame, I walk into it and hope it is a Pokemon and not a Item? If it is an item, I walk a bit more while still being under the next 128 steps?I've noticed you've been looking for an answer to this question for a while. Abusing a shaking spot is is essentially the same as abusing a wild pokemon but you're going to have to go at it with just a slight difference in approach. It's the same as non C-gear abusing a wild pokemon, the only difference is that you have to make some frame advancements to give yourself and the game an opportunity to throw a shaking spot at you. Abusing shaking spots doesn't happen with spreads on frame 1. Go a little higher. If the shaking spot happens to be an item, don't worry it doesn't screw up your advancements. You can either decide to move a little more hoping the game will throw another one at you but moving too often might have you frame advance again or repeat the whole process again.
I will try this^^
