Smash Ace
I found that hitting with an Up B and following it up with certain aerials (up air especially) immediately after the up B hits will send marth up in the air very, very high. It takes around 5-6 seconds for him to fall if you fast fall. I am not sure if the Up B was grounded or in the air.
Homebrew method on the Wii, if that matters.
