Can Falco shine Fire Fox

There are 2 types of Powershielding. When you enter full-shield, the following happens:

1. The first 2 frames are ineffective
2. The next 2 frames are used to Powershield projectiles and physical hits
3. The next 2 frames only Powershield physical hits

Against Projectiles:

• Time Window is 2 frames
• Knockback is cancelled
• Hitlag is cancelled
• Projectile ownership becomes yours
• Projectile damage is halved
• Projectile is sent back in the opposite trajectory

Against Physical Hits:

• Time Window is 4 frames
• Knockback is increased
• Shield is cancelled (means you can do anything you want after Powershielding)

Also if your Full Shield get hits by a projectile on the 5th frame, it won't get Powershielded, but as long as you remain in shield mode, the next physical hit you receive will be Powershielded, even if you switch to Light-Shield.

I am more of a technical-knowledge player than a practical-knowledge one, so feel free to be skeptical of this.

According to this frame data thread, Falco can't grab the edge for a whole 24 frames after he starts the Phantasm. From my own testing, walltechs work like this: 6 frames of intangibility on the wall followed by 8 frames off the wall (which can be interrupted and will continue into the input move). So if he does it perfectly, you have a window of 16 frames to hit him.

The problem is that you're probably (and expectantly so) hitting with an early frame of the dair (say 5, the earlist hitbox). You can't do anything until frame 49 of the move, and that's more than enough to go through the edge-tech. So, the best piece of advice I can give is to hit with a later frame of the hitbox, which will leave you more time to end the move and start the fast nair or bair before he grabs the edge.
