Hmm, for this kind of folder, imo DU would be better than stunknuckle. This way, just use DU with an elec support (+para), and DU will not only break shields, but also stun ur opponent. I think... This hasnt been tested by me, but it's worth a shot.
And yea, use areaeaters, trust me, its best to get extremely close for this kind of folder. Usually, 2 rows away, cuz flshstrike hits in a T formation. I have tried to make this folder before, and to be honest, it has a lot of potential, but I gave up on it. If you can manage to keep ur opponent in at least 50% blinded, you'll manage to dodge most attacks.
Let me note to you some problems I had in making this kind of folder. The first is getting the flshstrike to hit. If done from far away, it requires a lock on right? When most people are blind, they will either shield constantly, or crab left and right. This makes it a tad harder for you too. If you use doubleeater, you wont need to aim, just go to the center point. However, when doing this, ur opponent can still lock on to you using diaglock even when blinded, so you need to be careful too. These are crucial problems that need to be fixed if you want this folder to be the perfect one.
On another note, 50% crown noise = all normal non dimming cards add a small blind effect. It doesnt last long though, so be careful with that.
