OK fine fine, I'll explain why this move sucks since no one else wants to.
There are a few reasons why this move is bad. I'm going to explain them in no particular order.
First, let's discuss the difficulty and danger inherent to trying to spike someone in the way shown in the video. Spiking someone with an Aerial Gerudo depends on THEIR body position, not Ganon's. If the opponent is a little to far into the stage, it's a regular aerial Gerudo, slamming them into the ground. This is not a bad move at all, but this is not the move we're discussing. If the opponent is over or just beyond the ledge, you will spike them into a ledge grab. Again, not really a problem, but not good either. If the opponent's body is positioned JUST right, you will spike them. The margin of error here is basically nil, because if they're too close, you'll gerudo them into the stage or onto the ledge as mentioned above, but if they're just the TINIEST bit too far....you will die in a Ganoncide. This isn't bad if you're up a stock or have more damage than your opponent and want to level the playing field, but again, we're not discussing Ganoncides. Basically, you can f*ck yourself with this move incredibly easily.
If they airdodge and you don't react soon enough to DI back towards the stage, you might find yourself slowly fall-specialing (new word) to your sad, sad death. If you come up short and land on stage, you'll get punished due to Aerial Gerudo's gross landing lag.
Look, I'm not going to chastise you for posting something that you believed to be new and helpful, but I have to wonder about how well you thought this through before posting it. I don't know anything about you, obviously, nor your Ganon playstyle, but it seems to me like anyone who plays Ganon would have been able to figure out how bad/dangerous this move was without even trying it out. I mean...your opponent is entirely in control of how this move will end up (Spike, Slam, or Ledgegrab). These type of high-risk low-reward techniques are hardly what Ganon needs to advance his game.
