What do you guys do against D3? It seems like my only safeish option is to slow-fall nair. Other than that it seems like a 50/50 mix up where D3 wins if he guesses correctly once.
I'm trying to full hop rising fair D3 like he's snake, but it seems to get me into trouble.
What do you guys recommend?
FH fair is really good vs DDD, you just have to make sure you land safely. DDD isn't mobile enough to chase you so you just have to keep moving. Footstooling him to land is really helpful as well. Slowfall retreating nair is pretty much completely safe on shield so falling with that after FH fair should net you decent shield damage or shield poking if you're lucky to set something up.
Cross-ups work really well vs DDD, just for the love of Marth's unfortunately short life don't do it at kill %s. If you get utilted at 50% yeah, it hurts a bit; but now it's stale and you can adapt from there. Dying at 95% sucks though.
Walk away dtilt is really good vs DDD, just make sure you're not doing that into ftilt spam.
Walking in general is unbelievably important vs DDD.
I really hate using myself as an example, but I played the MU somewhat well in my MM vs 4GOD a couple months ago:

Some things I did very wrong, I was way more scared of ftilt than I should have been. My Dolphin Slashes were obviously stupid. Ignore the majority of the Shieldbreakers- I'm terrible and don't know how to input attacks apparently. Probably the biggest one is I didn't take full advantage of situations and apply all the pressure I could have.
Oh, and when he's offstage, after his second jump in the air, his jumps don't take him anywhere anymore. Just grab the ledge and force the upB and keep knocking him back out again.
