DDD-seriously? DDD doesn't have anything on Olimar besides gimping, which can be completely avoided by just camping and running away when he gets too close. You can throw pikmin over ftilt, and that clears out any options he has to approach. You can shield grab everything else. Everyone has the advantage over Olimar regarding recovery. It's not enough to change it to even IMO.
Lucas-I actually agree here, but I think Ness is even with Olimar. Have you fought Seanson? He's a beast.
Snake-uggghh, I hate talking about this matchup, cuz it confuses me. You just have to camp while you throw your pikmin, WHILE YOU'RE STANDING. Don't SH your pikmin throw against Snake cuz he'll dash in with his mortar slide. His attacks aren't fast enough to kill the pikmin, without getting grabbed from the after lag. You can shieldgrab ftilt. Just shield shield shield against Snake. His throws don't kill very well, so just risk getting grabbed. You can spike his recovery so try and dsmash more than fsmash cuz it'll send him at a lower trajectory. His cypher won't get high enough after the dsmash for you to miss getting to spike him.
Wolf- I don't have enough experience to go in depth about this matchup.
Fox- I've fought a good fox, and I'm not sure about this one. I know you have to be very mobile to win this one.
Wario-We've discussed this matchup in the matchup thread. I just checked Blueshells wario guide and he agrees as well that it's even. You have to uptilt dair and move around a lot. If you stand in one place the entire match, you'll lose.
Rob: I'm not really sure about this one either. I know Olimar has the disadvantage, but as to how big a disadvantage it is, I'm really not sure. 65-35 or 70-30 both sound about right.
