With the new patches making dsmash and nair pretty useful, here's my list:
A:
Uair-crazy good kills, combos, spikes, jablocks, what does it not do?
Dtilt-such amazing range, kills, combos, missed tech followup on 2/3s of the cast(many high tiers aswell)
Ftilt- fast, great angle for edge guards, missed tech follow up on 1/3 of the cast(some high tiers aswell)
Gerudo-goes through shields, sets up reads + missed tech followups on 3/4 the cast
B:
Usmash-Fast, REALLY lethal, way less end lag than expected so it's good for punish hungry opponents(usmash>dtilt mindgames OP)
Fair-great kill power, good range, 18%, generally makes challenging ganon in the air scary
Nair-combos, SHFF nair is great for neutral, 22%, lowest lag of any air action
Darkfists-amazing kill power, solid OOS, hold down while recovering to the edge to put what is essentially a smash attack there, generally amazing.
Dropkick-good for recovery and approach, I'd like it more if I had more practice with it though.
Aerudo-GANONCIDE, keeping people off you while you recover, punishing shield breaks at low %s
C:
Fsmash-extremely deadly, something like 40+% fully charged, so good for shields break punishes at low%, catches spotdodges if they're conditioned to spotdodge dtilts and ftilts, good for reads(roll behind after missed tech gerudo)
Dash attack(Ganon Truck): has super armor, gets in, sets up combos, solid move
Bair-edge trumps, combos, solid 16%, wish it had more range for RARing short dudes like pika
Dair-best meteor, sets up for combos
Dsmash-good now, better than most fsmashes, risky OOS but rewarding, catches rolls
Wizkick(Ganon Train)-meteors, vague recovery mixup, scares people, lotsa %, catches rolls/landings
Flame Chain-Great for rosa(kills luma), but gerudo's probably better for everyone else
D:
Warlock Blade-the SWORD! Breaks shields too
E:
Grab-crap range, some follow ups from dthrow, but not enough...
Ganon punch-fun, but only for punishing rests/shield breaks, suck to do on accident
Utilt-fun, breaks shields, kinda good for edgeguards...
Z:
Dark Dive-EEECCCCCCHHHHHH, less damage than nair
, never ever kills
