It is common knowledge that Marth is good at grabbing himself. Hmm. Let's hear some more suggestions and I'll update the first page.
Here is a quick guide to chainthrows, I don't have a LOT of time atm.
Fox:
0-20ish% you can uthrow repeatedly straight from 0%. Note that closer to 20-23, a really good Fox player can DI not AWAY but up or something, and then shine before you grab. Which brings us to the next point.
22-30% you can just upthrow if they're still dumbly DIing away, thinking they can escape. However, if they don't DI, it is extremely hard to just uthrow grab, esp. at 24%. Here you "ken-dash" (as it was called 3 years ago), which is a very short and quick pivot-grab. That is, you throw them up, dash either direction and immediately turn around and grab.
31% If they DI away, you can just grab again, or you can utilt. If they don't DI (and try to shine or jump), you can just turn around and utilt to grab.
31-37% If they are still DIing away, you grab them still. BUT it is often better to walk -slightly- to the way they DI and utilt. Try NOT to tipper utilt at this percentage.
45-50% Try for the non-tippered utilt to fsmash. OR, if they don't DI, and are closer to like 50-70% (I've seen even higher, actually, but maybe the Fox missed hte jump), you can walk SLIGHTLY to the left or right and TIPPER FSMASH right at the top. This is ****. They end up with like 70%. total.
55-60% If the above didn't work for you, but you somehow got a grab again (maybe you soft utilt->grab), now you have to uthrow to uair. A non-tipper uair will let you get another grab. A tipper uair will let you get a PERFECT tipper if you space yourself right. This is -ideal-; you'll see M2K doing this all the time against PC. Simply because if your Fox is at like 58%, and you get a tipper uair, he'll be at what, 70? Then you get a tipper, and he'll have just been hit by Marth's strongest move and end up with 90%. A bad DI and he's dead-- a good DI and he'll be off the edge, or ready to swipe off the edge with a ftilt or fair.
I guess while I'm at it, if you screwed up but you got another grab at like 70%, you could:
- go for a nair, and follow him
- go for an uair and mindgame another grab
- uthrow and hope he doesn't DI, walk slightly->tipper
- sh , wait, fair (hope he DIs against you like a silly joe), and fsmash.
- reverse up+b
And yeah, that's pretty much it. I'm kinda too tired to do one for Falco, but the main differences are:
- You can't always start the chainthrow at 0% with falco. Normally you have to fthrow->grab really quickly. At like, 9% you can uthrow.
- Falco accelerates to the ground faster than Fox, so you can juggle him with utilts a bit better. I don't really know how that works, since g= 9.80m/s^2, and the air friction on a bird should be WAY more than air friction on a Fox. Just remember he's a tad bit heavier vertically, but he accelerates down faster. A lot of the combos and percentages are extremely similar, maybe a few percentages up.
FUN FACT: If you grab a falcon at 60%, uthrow always. If he DI's fully, he will eat a tipper, every time. If he DI's not fully, you can utilt->grab or utilt->fsmash. Fun fun Falcon.
=( I'm hungry, peace.
