I think FoD is good against falcon because of the small stage aspect. Yoshi's and FoD are always good picks in the mu IMO. While platform heights screw you up, they also screw up the falcon, so that's kinda negated. The only thing I don't like about it is that I like to be as lame as possible when edge guarding falcon and just stay on stage and up air. On FoD, this doesn't work because the mid-height platforms screw up your up airs. Just think about falcon's recovery choices etc and go out and get him. A little more risky, but just as effective. You can't let a falcon back on stage. Not with that neutral game.
For jiggs, I don't have much experience in the matchup, but I'm learning it bit by bit now that prince abu and Mr. F are in Chicago. I like it. I think it may be up there with yoshi's as far as counterpicks go. Nice, techable walls, small horizontal blast zones, and the platforms aren't usually a problem. At the same height that jiggs can up tilt through the platform, you can stomp and it'll hit. Only obvious problem is the high ceiling. If you get rested, your go-to should be a stomp to trade stocks and that isn't always the case here.
Marth on FoD is my least favorite after FD. I might be biased because Ripple almost JV5'd me on the stage when I first started playing (7% baby let's gooooo), but I always seem to have trouble on this stage against marth. Edge guarding is hard, and the platform heights make up tilts and fsmashes stupid free for marth. You could fake out the timing with a double jump stomp or whatever, but it's not worth the risk IMO especially if you don't have your jump afterwards.
I'm not crazy about the stage vs falco tbh, but 99% of falcos tend to hate it, so I'll just take them there anyway, if it was the 1st / 2nd ban when stage striking (pay attention to this). That's just me.

congrats on 2nd though. Looks like moon got his revenge, huh? Yea, it's good you're thinking of the marth killer though lol I remember watching you vs moon at big house and seeing how many missed opportunities you had to use it. Read Ace's edge guarding thread, I found the section vs marth to be particularly useful. If they land on stage, just dthrow into bair. Reset situation. I think you can probably just react to them teching, too, if they're at that % where they tech on a platform.
Glad to hear you're finally gonna start being more technical LOL we've been saying it for years. Your spacing and option selects are already the best right now, all you need is that tech to open up more possibilities, specifically defensive ones. I also don't see you do the shield DI as much, or maybe I'm missing it? All I know is that it works on the likes of KJH, Kels, and SFAT, so it's legit, even against fox (but more so against falco).
