Figured I'd drop this in raw from a ramble in the Wario skype group. Hope it helps someone out.
Longer response incoming, but do you have c-stick roll buffering in your toolkit? I may've already asked
[8:28:31 PM] Agi: It's a option for escaping spacie shield pressure, along with just holding shield longer
[8:28:41 PM] Agi: Frame traps are real
[8:30:02 PM | Edited 8:30:27 PM] Agi: As far as the combo game goes, the UThrow CG is only guaranteed to about 20%, at which point he can shine out with no DI and good timing - which you can respond to with USmash or UTilt
[8:30:54 PM] Agi: Or probably SHAC UAir though I've yet to really work that in
[8:32:29 PM] Agi: When comboing Fox you really want to focus on the vertical axis, FAir loses utility quickly. I basically use it at low % on grounded Foxes to set up a grab
[8:36:24 PM] Agi: UThrow is good at all %s for regrab at low, USmash/UTilt at midlow, UAir at mid, BAir/sourspot UAir/NAir at midhigh, as well as sealing with a waft at 80%+
[8:37:01 PM] Agi: Sourspot UAir to BAir is also super good around that range
[8:38:03 PM] Agi: Fox doesn't actually go into tumble from chomp until 24% or so, so you can get a regrab off of falling chomp pretty reliably
[8:39:02 PM] Agi: And of course aggressive ledge camping while he's trying to recover can make landing that NAir all the easier
[8:39:48 PM] Agi: Only go for side B if he doesn't have his jump and he's being indecisive about side B over up B
[8:40:10 PM] Agi: Many Foxes won't up B unless they're below the ledge level
[8:41:02 PM] Agi: And while side B CAN knock him out of the charge animation of up B, it can only do so in the first few frames before the protective hitboxes come up
[8:42:07 PM] Agi: We can jump out of UThrow UAir, SDIing shine makes it super manageable
[8:43:10 PM] Agi: And if you can ever manage to land a DAir on him onstage
[8:43:20 PM] Agi: At any % above 35
[8:43:25 PM] Agi: He should be dead
[8:48:52 PM] Agi: So yeah, combo him vertically, KO him horizontally. Regrabs, techchases, and UAirs (strong and weak) are your friends for combo extending, and UThrow is your go-to. Use side B sparingly as always as it loses not only to shield but to his shffled NAir. If he gets offstage, it's not a free kill, but you certainly control the situation. We are pleasingly safe from shinespikes more than most characters because dat disjoint, but he CAN manage it. Our NAir is great as a panic button as always
[8:49:53 PM] Agi: I uh, hope there was at least -some- new information in that that'll help out
[8:50:52 PM] Agi: Oh yeah and our DTilt is a trap in that MU
[8:51:05 PM] Agi: He just NAirs over it and lols
[8:51:50 PM] Agi: Only really useful as a shieldpoke or followup from FAir at low %s
[8:52:00 PM] Agi: Though it can also push him to ledge
[8:58:51 PM] Agi: Dammit I scared everyone away
[9:14:13 PM] Agi: DThrow with your back to the ledge > fall after > NAir on reaction is gr8 too
