Yeah, sorry for the potato-cam. It's all I got right now. :^B
Here's the moveset in greater detail:
Standard attacks:
Jab: A triple slash. 1st horizontal, then vertical, then another vertical.
Dash: Isaac's iconic jump strike.
Tilts:
Side Tilt: wide horizontal slash
Up Tilt: half arc slash
Down Tilt: low sweep
Smashes: Now this is where it get's good. Isaac's gimmick is djinn. Every smash and aerial Isaac does will use djinn. Every attack has it's own set djinn, each with their own special properties, that it can use. Some power the attacks up, but most will simply add a special property to the attack. However, the catch is that every time you use the djinn, it goes on standby/recovery for 5-10 seconds. It's similar to Robin's but you won't be gimped very much unless you use the same move over and over again.
Side Smash: Briar+Sap - Sap makes it so that Isaac recovers half the damage he dealt to the opponent.
Up Smash: Spire+Flint - Flint increases both the damage and knockback by 50% if Spire his the opponent. This is basically Isaac's go-to KO move.
Down Smash: Sand+Petra - The next move the enemy uses after being hit by Petra's attack will just flat out not work.
Aerials:
Neutral Aerial: Gaia+Granite: This is a pretty long move; Granite makes it so that Isaac is invulnerable through the entire duration of the attack.
Forward Aerial: Thorny Grave+Geode: Geode makes all the ghosts in the attack will meld together into a sphere and just stay there for like 5 seconds. It acts like Zelda's Dinn's Fire in Project M.
Back Aerial: Skull Splitter+Bane - Bane poisons the enemy by way of a flower.
Up Aerial: Grind+Echo - Echo increases the damage by 100% if it makes contact. This is a multi-hit move.
Down Aerial: Rockfall+Ground - Normally, Rockfall is a semi spike (like Kirby's Dair in Brawl), but with Ground, this move becomes a true spike. Edit: This is basically like Megaman's Dair.
Special Moves: Isaac's second, more minor gimmick, is that he can charge every single one of his specials to power them up, and perhaps turn them into a stronger version of the same attack. The way you charge Isaac's moves is less like Mario's FLUUD and Lucario's Aura Sphere, and more like Squirtle's Water Gun in Project M, in that you need to hold the button to actually charge it.
Neutral Special: Ragnarok/Odyssey - Ragnarok is a simple move that attacks in front of Isaac. The closest thing I can compare it to is Ike's Eruption. Once you charge it, however, it turns into a wide range KO Punch! Although it's much weaker, to balance things out a little.
Side Special: Move - Unlike the move Isaac used as an Assist Trophy, this version is slower and has a much shorter range and can actually damage. It also has reflecting properties, so you can compare it to Paletuba's Reflect move. It's charged version is much faster and has a longer range. It's also a fist instead.
Up Special: Retreat - Isaac transforms into a million tiny bubbles and you can (sorta) control them. Where they converge is where Isaac reappears. The charged version is easier to control and travels much farther, like an invincible version of Villager's Up Special.
Down Special: Quake - Isaac simply lifts up panels of the floor to damage opponents. The more the charge, the more they quake.
Final Smash: Judgment - For the sake of Smash, Isaac uses 4 Djinn to transform into Judgment and fly up to the central top of the screen, where he then proceeds to fire a laser downwards to annihilate his opponents. This attack is basically a thinner version of Lucario's Aura Storm, but with smart bomb style explosions at the point where the beam hits the ground.
Grab: I forgot to draw these, so just use your imagination. They all use the large, gloved hand.
Grab: Catch - The attack has a similar range to Link/Samus' grabs and can even be used as a tether.
Pummel: Grip - Isaac squeezes the opponent.
Forward Throw: Force - This isn't really a glove move, but hey. Isaac throws the opponent forward and proceeds to punch them with Force. It looks like a large fist.
Back Throw: Smack - Isaac throws the opponent backward then b-slaps them with the gloved hand.
Up Throw: Scoop/Carry - Isaac throws the opponent on the ground then uses Scoop and Carry to throw them back up into the air.
Down Throw: Crush/Pound - Isaac throws the opponent onto the ground then crushes their skeleton with Crush and Pound.
Taunts:
Taunt 1: A random Golden Sun emoticon appears beside Isaac while he poses.
Taunt 2: Djinn of various elements swirl around Isaac.
Taunt 3: Isaac uses Sabre Dance and 4 random swords/blades from the Golden Sun series appear beside Isaac.
