Thanks for the compliments/advice everyone. I've tried DIing straight away from Marth's f-throw in the past and have somehow managed to get tippered almost every time >_<. Eventually I just figured it would be better to DI towards him and just eat the f-smash instead of getting tippered and losing a stock at 20%, but I haven't tried DIing down and away, so I'll give that a shot.
The first is that you're not really comboing. You're going for the bthrow at medium percents, which definitely isn't going to kill.
I know d-throw is usually used for tech-chase setups at low percentages, and I do that against most characters, but against Gubian it tends to result in him poking me in the face with a f-air/forward-b before I can follow it up, forcing me to shield and putting me back on the defensive. I've tried a few things here and there, and occasionally a forward-b can pull him out of whatever attack he's trying to use, but I haven't been able to get anything solid (like a f-air) to connect after the throw. Eventually I just started b-throwing him and wavedashing/teleporting after him to try and keep some pressure on. Maybe I'm just not moving fast enough?

He does the forward-b after the d-throw at about 7 seconds into the match, and a second time at about 2:34. A down-b seems to be able to pull him out of the forward-b after crouch canceling the first swing, but I'm afraid that would get pretty predictable and it doesn't do much good against a f-air. Maybe an upward angled f-tilt instead? Or should I just back up a bit, let him miss the attack, and then punish him in his lagtime?
And yeah, I know Gub's not that great (he also just doesn't play the game or practice as much as I do) but he's really the only person I have to practice with
. There's a tournament near here in late February though, so I'll get some good practice in when that happens. Hopefully I won't be getting tippered after f-throws by then too
