I'd like to pretend Tabuu didn't happen, even if I did make that epic GMV based on the SSE.
Now for the dual-sword Ganondorf moveset.
B: Gerudo Flip
This is a mix of Cammy's Hooligan Combination and Akuma's Demon Flip/Hyakkishu. This move is one of Ganondorf's best ways to approach as his speed isn't great. This move starts with Ganondorf flipping in the air toward the opponent. Here are the inputs for the types of attacks he gets while in this state:
B: Stab to behind, to counter anyone trying to roll to get behind him.
Side B: Grabs the opponent's head and knocks them to the ground with a ground bounce. Counters blocking.
Down B: Does an inward strike with both swords while diving in. Counters anyone rolling back to evade.
Up B: Stabs forward, countering anyone jumping away.
A: Cancel out of the jump, can be used to counter spot dodgers. Allows you to use any attack available to you.
Doing nothing just gives you a nice forward jump.
Side B: This move is a rekka type attack like Marth's Sword Dance.
The first move is a low swing to the ground. This move is safe on block and a nice spacing tool as Ganondorf moves a bit for this move. The second hit is Ganondorf lauching the opponent into the air with him following up and then here comes the fun part. Depending on what you want to have for your reward, there are three options you can choose from:
Hit #3:
Up-Side B: Ganondorf does a fierce attack that sends the opponent straight up in the air. Used as an aerial reset as Ganondorf, if done from the ground, can go straight into a double jump to keep on the offensive.
Side B: Strong dual stab that sends the opponent flying horizontally. Used for horizontal K.O.s and to regain control of the stage. This is the strongest of the three outcomes as no mixup potential is available from this.
Down-Side B: A downward strike to the opponent. At higher percentages, this can spike. Other than that, this can be used like Side B, but with the bonus of having a tech chase.
Down B: Big Mistake
Ganondorf enters a parry stance and if attacked, he grabs the opponent, whether they're in the air or not, and does the famous choke move in Brawl. Has all of the followups you've seen in assorted mods. The biggest weakpoints for this move is that it's weak against grabs and cross-up attacks like Fox Illusion and aerials that leave the opponent out of Ganondorf's grab range.
Up B: Winds of Death
This move is essentially like MvC3 Jill's Machine Gun Spray hyper. Ganondorf takes a leap, doing a slide flip with both swords extended. If the last hit lands, you get a ground bounce.
Ganondorf is still a heavy hitter, but now he has the range, mobility options, and the mixups to compensate. He has great horizontal recovery for a heavy character, but his vertical recovery is lacking as a result.
I'm surprised I managed to come up with that while keeping it very Smash-like.
