Ike- You can pretty much expect Ike to be a beast from his range and his killing power. However, it isn't as bad as if you were using Meta knight against him (Ike owns meta). Things that really work against Ike is a short-hopped PKfire. One, if he tries to do any sort of short-hopped aerial, the pkfire would hit Ike and push him away. Two, PKfire ***** Ike's forwardB recovery. Three, PKfire is great for baiting him and punish. Of course, one move doesn't make up for the fact that Ike out ranges you in every other move. His aerials completely shuts down your dair, since all of his move cover above Ike, making it incredibly hard to set up the right height level to dair. And you'll often trade hits with fair with his aerials (and trading hits with Ike is like trading hits with Ganon in melee). You're ground moves are solid against Ike though, especially the ftilt. The other two tilts lack range and will often whiff, allowing Ike a free ftilt or the like. Your smashes are generally better (just watch out for Ike's sweeping UpSmash).
-Be sure you punish obvious rolls with a dashcancel upsmash.
-Spam PKfire
-ftilt after an aerial 75% of the time.
-Don't get hit (easier said than done, but its so key)
-If the Ike wants to approach you with an ForwardB, use a short hopped PKfire or just jump over him. It's practically impossible to time a roll or a ground dodge because Ike's ForwardB is amazing as a spacing mindgame. So just make him stop using it with a short-hop PKfire.
-Harass his ForwardB recovery with a PKfire and a PKthunder
-Try your best not to get annoyed by Ike's neutral jab combo (its so easy to land and it does friggin 15%) its pretty much the only ground move Ike has going against Lucas
Captain Falcon - You shouldn't have trouble with him. At all. Imagine melee falcon without the ability to upair combo and you dominating the ground game (ftilt *****, uptilt for combos, dtilt can force trips sometimes). And ofcourse, use short-hopped PKfires and bait with fairs. Just watch out for grab spamming Falcons and punish with fairs, ftilt and the like. The only thing scary is being upaired while your trying to recover but you should see it coming.
(Be sure you use ftilt right after you land with fair/nair since ftilt comes out incredibly fast and has insane range for a tilt. Almost gurantees a safe landing.)
DeDeDe His ForwardB (him chucking the WaddleDees) is as spammable as the PKfire so space well. He is obviously, much bigger than Lucas so your nair absolutely dominates D3 by the fact that his shields won't cover him fully when you nair. So spam your aerials. He also has an absolutely horrendous recovery, so the bair meteor, or the downB hit is incredibly easy to land for an easy kill. However, watch out for his chainthrow; I think he can get two-three at low/mid percentage. But even then, a good D3 will mix up the dthrow chainthrow with an occasional upsmash/dashattack expecting you to spotdodge/roll and kill you. Another thing, your smashes near the ledge is a safe move to do since even a shielding opponent will get pushed back far enough for a forced edge grab. Allowing you an easier situation for a kill (if you anticipate that he'll jump the ledge->upsmash, otherwise, roll and forwardsmash/ftilt/dsmash). uptilt is also incredibly easy to land on D3.
Meta-Thank god Meta doesn't have a projectile. Spam PkFire like no tomorrow (short-hopped). And majority of the time, you should aim to kill him vertically since its much, much easier that way. You practically can't edgeguard a good meta when he's recovering horizontally. His fair is overall better than yours, and all of his aerials come out as fast/faster than your nair. Anticipate rolls (if there was something as easy as wavedashing, meta will be unstoppable imo) and punish with ftilt/upsmash. Never underestimate the range of the upsmash, since it hits like three Lucas models piled up (sorry for the lame description) and also hits a decent amount at the side.
-Meta can close distance really fast with a nicely timed DownB if you get predictable with the PKfire
-Meta can **** your recovery with a dair off the ledge
-If you try to stall at the ledge (which isn't a really good idea in the first place with Lucas), he'll **** you via running nair off the ledge
-Watch out for his upair combos, out of his fthrow. Your dair is solid though.
-Do not PkThunder as recovery if you don't have to. The more time you spend off the level, the more chances Meta has to kill you
Will update with Wolf/Pit/Olimar/Marth/Diddy tomorrow.
EDIT:
General tips
-If you're DIing backwards with a shorthop and you do a Pkfire, the move won't come out in time. So you need to full jump and time near landing when DIing back.
-Ftilt is like God. If God was a flashy hexagon of ****
-Never, ever spam your grab. Taking in the fact that your grabs is a grapple-type (grapple-types come out slow and is so easy to get punished), any good opponent will spotdodge and **** Lucas. Not to mention it has ****ty range (That doesn't mean you shouldn't use it at all. A dthrow at low percentage is a perfect set-up for a dashcancel upsmash.).
