Overview on the cast
A mix of 64 and Melee Jiggs. Higher gravity means she can gimp more than regular Smash 4. Also, Rest combos.
Smash 64 Samus. She gains nothing from this mode as she loses recovery and her aerials suck. The only thing she has is Isai Dair combos but they are techable.
Even if his recovery is nerfed he has a better air game. He can use Fair, Uair and, Nair without getting punished hard and also combo with his ground moves. With higger gravity his tilts combo more and lead to KO Punch.
While he doesn't have roofio kills he now has juggles and with lagless aerials and speed he can be untouchable. Recovery is garbage though.
Trades the Boss combos with other set of combos. High gravity make his aerial movement less awkward.
Complete beast with Buster mode and a nightmare with Smash. Recovery sucks though.
Melee Sheik that can't kill reliably unless she goes out to gimp.
Improved Melee DK. Except recovery.
With L Cancelling back he is way better than regular Mario. Even if his recovery sucks.
Nothing big here except a better Dair and better followups.
Melee Fox with no short hop laser. Shine is slightly more useful.
Can do Ken combo and combo to Shoryuken. Except for a recovery that is garbage unless you use Up B 2 (Beat) SLHG MM is in every way superior to regular MM.
Combo master along with gimp power.
ZELDA CAN COMBO! Better air game and throw game in general.
Get BizzaroFlame. Recovery is garbage without customs.
Brawl Marth which is not a bad thing. Give him/her Dashing Assault and you have a high tier. Lucina is legit.
Aside from Knee's nyeh lag this is Melee Falcon with some 64 stuff.
Infinitely better air game. Recovery sucks.
Way better. Give him some custom moves and he is a beast.
Brawl Meta Knight with nyeh kill moves and worse jumps.
Project M Kirby with Smash 4 moveset.
Project M Charizard with Smash 4 moveset.
Oh my, he has a legit air game and grab game. Recovery is complete garbage without Up B 2.

: Improved throw game and air game with nyeh recovery.
: Close to Melee Peach.
: Ike can combo oh my!
: HAHA. He can no longer hoo-hah and his recovery is GARBAGE. Still good with combos.

: Hey, DDD is actually good.
: Trades his Smash 4 gimmicks for better gimmicks and useful aerials.
: P:M Lucario with Smash 4 moveset and gimmicks.
: DAIR AND U-TILT HAVE USE OH MY! Aerial beast with lots of killpower.
: Some new gimmicks that come with a nyeh gimpable recovery and getting comboed to death by Ness, Mario, Sheik and basically everybody.
: No real changes while still being a beast of destruction.
: aMsA's Yoshi came back stronger and deadlier. Recovery sucks really hard.
: Better followups along with custom moves make her a strong machine of destruction.
: Sheik clone with a sucky grab.
: If his air game wasn't a nightmare already Killager has an even deadlier air game. Along with a good recovery he is a gimp master.
: Smae ol' tactician except that he/she has better aerials and combo ability.
: Beast of the stage with nyeh recovery.
: A 100 times better character with L Cancel and followups.

: Smash 64 Link. Slightly better than the original but still a nyeh character.
EDIT: Forgot Rosaluma
: Rosalina is still top tier and now she has air game. But she is slightly easier to kill.
