Wrong.
COUGH COUGH
Falco, Jigglypuff, Kirby, Ganondorf, Zelda, Samus, Yoshi, Palutena, Peach, Mr. Game and Watch, Bowser, King Dedede, Marth/Lucina, Ike, Bowser jr, Shulk and it surely goes on.
These are all characters that have no real confirms at kill percent, or have to perform something that in turn puts them at a risk upon whiffing(whatever level of risk it might be but it is usually punishable)
Luigi didn't need to be able to confirm a kill out of a throw, same as I honestly think Sheik should not be able to Dthrow you into a guessing game for your life(you jump or airdodge and the other upairs or uses vanish. Look at all this SKILL in guessing), or everyone has it or nobody has it! That's how it should be.
Wrong about a good portion of those.
-Ike can just space with f-tilt and auto-cancel fair and bair, no real risk. You don't use his smash attacks to kill unless you're sure and eruption pretty much claims your win with a ledge trump assuming you miss the bair. Btw uair covers air dodges reaaaaallllllyyyy well especially if you fast fall it at the right time.
-Ganondorf in the current patch can basically get you stuck in shield with u-smash spam, and his bair also autocancels, but that's where it ends. Nothing else about can be considered safe unless you auto-cancel uair and even go as far as hitting with the latent hitbox of it. Btw U-smash ends pretty damn early so using it with a mix of uair and bair when someone lands guarantees a hit or two.
-Mr.Game and Watch literally just needs to spam d-throw and side-b, he also has easy set-ups with bucket on projectile characters and his u-smash has invincibility, meaning you have to absolutely respect him when he is under you, a very easy kill confirm.
-King Dedede has good kill confirms with gordos due to edgeguarding, uair due to the long amount of active frames and the insane range making it very hard to avoid getting hit by, and a jab akin to DK's which traps you in and lets him set-up nicely for kills and grabs.
-Marth/Lucina only have jab. That's pretty much all I have to say, only set-up tool for confirms they can use reliably, uair footstool dair spikes to tipped f-smash or u-smash are too hard and unreliable to get. Also up-b OoS if they whiff on shield, but that one is slightly putting you at risk. At around 120%, you can also use an untipped d-tilt for a tech situation and assuming they miss the tech, you can u-smash them so there is another kill confirm.
-Kirby has dair, seriously what made you put him there? Dair leads to every single thing, including a shield break with a SH down-b if your opponent is keen on staying in it.
-Zelda pretty much only has up-b OoS for a good kill confirm. Which btw she has the ability to reliably mix-up well by teleporting in spot to the left or right of her, or up above, she can also control the distance to some extent using the floor. It has very little risk obviously but in the long run it helps, I also believe her d-tilt is kind of ok.
-Shulk's monados make him so adaptable that he can literally wall of death you to the blast zone or break your shield easily, there is quite literally no reason to put him there.
I'd also include Falco and Samus, but I'm tired of typing a paragrah and I really have no reason to include Yoshi because again why put him there? Yoshi has kill confirms, you just never played a good Yoshi. Falco has a very strong off-stage game and can get kill confirms with dair assuming you know the quirks. Samus literally has projectiles and bair to space with, and I believe you can combo zair to u-smash with her at higher percents, giving her a kill confirm, also her u-tilt spikes.
