Seriously, dude, I understand that Ganon's D-air has a lot of hitstun in Melee. There are a few moves like that, but not -nearly- as many as there are in Brawl+. Squirtle can u-throw to u-air until about 100%, and u-air kills at that percent. Lucario can do the same.
Captain Falcon can do half of his moveset to combo into knee, which kills (with proper DI) at around 90%
Ganondorf's F-air kills even earlier than it does in Melee (don't listen to what BigLou/BBQ say). Character just jump slower than they do in Melee, so it's not as deadly, per se
Overall, Brawl+ has Bread n' Butter combos that are extremely effective and can guarantee deaths most of the time.
Yes, I'm ragging on Brawl+. I do enjoy playing it more than Brawl, because I actually have to worry about getting hit, and my hits are more effective because they combo into stuff. Particularly Ike's Fsmash
Ike, though, has 2-hit combos at best, which is why I think he'll forever be bad :/ They just have a lot of knockback and damage output, so 3 2-hit combos are deadly.
