My experience bud. It's good if you can point out that some of the things I say are wrong or don't work for you or many other people, but I'm not intentionally giving "bad advice". I never said anyone had to follow my advice. It's just works for me. Sometimes, some things just don't work for people just like all Peaches (perhaps I should've said "First Approach") and Marths don't play the same way. Sure, they use similar techniques and may like something that they see and use that, but everyone enjoys their own playstyle or else the game would be kind of lacking in several areas, much?
Anyways. You seem to have much more experience than me, so if you think you're absolutely right, you probably are. But don't be so quick to judge on the way other people play. Instead of just saying Marth dies a lot with a low ceiling, try to point out why and what moves Peach has to KO Marth vertically. And about Poke Floats and turnips, Poke Floats may not be the best choice of a stage for Marth. I'm just pointing out some things that I do because Poke Floats happens to be my worst stage. And then, even if Marth is bad at stages with a low ceiling, there probably are other strategies to keep Marth from dying.
My tricks? You're right. These are all just standard attacks that can be used at certain times. I never said there were anything significant about them.
But thanks for corrections. You're indeed right. Peach does have a lot of chances to pull some turnips and pwn Marth on Poke Floats, but it requires quicker thinking than...let's say FD. Even I wouldn't take Peach to Floats normally, seeing how there are better stages. But a lot of Peaches have taken me to Poke Floats.
Now, vertical K.O.'s is my typical favorite way of getting rid of Peach. I see it can have a lot of problems but as my ability to WD is very low, it doesn't take much ability for a Peach to dodge several of my attacks and pummel me in lag. And I see how saying "Vertical K.O.s are not the best bet" contradicts my idea of individuality so I take that back.
I'll edit my post, and thanks for pointing some stuff out that I was missing.
