I will add on Charizard when I'm done...
Before I being, please read
this guide about Pokemon Change's mechanics and how it affects PT's stale moves, stamina, etc. It's an interesting read and you will probably learn something you never knew.
Pokemon Trainer:
SQUIRTLE (aka Wario's little cousin)
What moves or tactics should we watch out for?
-Jab: A pretty decent move considering they come out fast and can be linked from a grab release.
-Utilt: This moves comes out super fast, can combo into itself, and can lock people when Squirtle is tired. Really good for small but quick amounts of damage.
-Fsmash: It has a small amount of startup lag, but the move does have some Super Armor frames.
-Usmash: This will probably be the most used smash. It creates two walls of water on both sides of Squirtle, protecting him from physical contact. It has some kill potential and can be combined with hydroplanting, shellshifting, whatever you want to call it. It has some startup lag.
-Fair and Bair: These two moves are basically the same move, except fair does more damage. They are basically sex kicks, so treat them as such. They both have potential killing power.
-Dair: Kind of like Mario's dair but much better overall. The last hit is the one with the most knockback.
-Dthrow: This is a kill move at higher percents depending on the stage. A good Squirtle will save this move until they are ready for a KO.
-Water Gun: A decent edgeguard move that can be charged. It pushes people away but deals no damage. However, uncharged does do damage, but most Squirtles will never use an uncharged one.
-Withdraw: This move has very limited uses. It gives Squirtle invincibility but hitting him sends him the opposite direction. Also, jumping on him flips him over and puts him in a helpless state. It can be used for recovery, but it's a pretty terrible option in most cases. You probably won't see this move very often, if at all.
-Waterfall: Squirtle primary recovery move. It protects Squirtle from the front and bottom. His back and top part are exposed to attacks.
-Pokemon Change: Switches Pokemon...using this causes him to switch out with Ivysaur. Basically a free punish if he does it while Lucario is on stage. However, there is a way for the PT to cancel most of the transformation lag time using moving platforms.
-MISC: He is light, floaty, and small. He can walljump, wallcling, and crawl.
What moves or tactics should we try to enforce in this match up?
-You certainly have more range than him with Fsmash, but Squirtle has more speed to get around this. Be sure you space yourself accordingly.
-Squirtle is light, so he'll die relatively early if you can survive long enough.
-Learn to edgeguard a Squirtle effectively. Waterfall does not give a whole lot of horizontal distance, but gives a decent amount of vertical.
Do you feel Lucario has an advantage in any particular scenario of this matchup?
-Squirtle has no projectiles (charged AS goes through Water Gun) or reflectors, so feel free to use Aura Sphere. However, Squirtle is fast, so be careful about how much you spam AS.
-Squirtle lacks raw killing power, so you should live to pretty high percents as long as you don't get KO'd by Dthrow. Once you have Aura, you know what to do...
Do you feel the opponent can shut down aspects of Lucario's game?
-His light and floaty nature prevent some combos from working on him. Keep this in mind.
-Squirtle's aerials are more superior than Lucario's and come out much faster. Lucario's fair can challenge his fair/bair, but his come out faster and have more priority.
-Squirtle can edgeguard a Lucario with Water Gun if you are using Extreme Speed. Therefore, be careful when you recover mid/high.
-When recovering low, be prepared for a bair/fair to the face. Also, watch out for runoff->bairs. This could lead to a stage spike.
Counterpicks? What to avoid and what to enforce?
-I'm at a loss here...I don't know what are good stages for a Squirtle. I guess big open stages that allow aerial movement are good for a Squirtle. Also, Squirtle relies primarily on vertical kills, so low ceilings are probably bad.
IVYSAUR (aka the lesser of the three...)
What moves or tactics should we watch out for?
-Dash attack: A surprisingly decent kill move at higher percents. Ivysaur is a hitbox while she is sliding along the ground, and it lasts a decent amount of time.
-Ftilt A decent multihitting poke move that is relatively safe even when shielded. Ivysaur leans forward while doing this move, so it's hard to shieldgrab when properly spaced. It also comes out relatively fast.
-Utilt: A decent anit-air move that hits directly above her. It can be used to dodge certain ground moves, since her hurtbox is lifted off the ground, but anyone who does this to avoid attacks regularly is werid...
-Fsmash: A decent kill move that is somewhat quick and somewhat hard to punish if spaced. You'll probably see it used more when you get into kill percents.
-Usmash: Undoubtedly her most useful kill move. It has a some startup and ending lag, but it can kill at somewhat low percents if you are hit. It's also disjointed and can beat out Lucario's dair.
-Fair: One of her possible aerial kill moves. It covers a large area in front of her.
-Uair: Think of an aerial usmash with less knockback and somewhat less range. Can propel Ivysaur downwards.
-Dair: Basically a upsidedown uair but with less knockback and can stall aerial movement. It can spike.
-Bair: Probably her best spacing tool, since very few non-projectile moves can challenge it, it has very little ending lag, and be spammed to discourage approaches. It does very little damage, but the primary purpose of this move is to annoy and space.
-Bullet Seed: A decent move if you get trapped in it, but you can SDI out. The initial frames can knock you into the seeds.
-Razer Leaf: This projectile has good priority over other projectiles, but is slow and can be canceled by regular attacks. Again, used mostly to annoy or force an approach. Can be angled.
-Vine Whip: This is pretty much her only method of recovery. It's a tether recovery and she can only use it once. As an attack, it's pretty beastly if you get hit by the tip, but it probably won't happen too often. It also has amazing priority (I don't think anything can clank with it, but my memory is fuzzy).
-Pokemon Change: Switches Pokemon...using this causes her to switch out with Charizard. Basically a free punish if she does it while Lucario is on stage. However, there is a way for the PT to cancel most of the transformation lag time using moving platforms.
-MISC: Can crawl.
What moves or tactics should we try to enforce in this match up?
-Be aware of her kill moves, especially usmash. Ideally, don't stay above her too much, because she has some decent anti-air moves. Her aerials are okay, but they have some startup time.
-If the Ivysaur starts playing keep away, throw some fully charged Aura Sphere.
-Taking damage is something an Ivysaur cannot afford. More damage equals more knockback, and this could result in death for an Ivysaur.
Do you feel Lucario has an advantage in any particular scenario of this matchup?
-Learn to edgeguard Ivysaur. Walls of fair or Aura Sphere could mean death. Don't be surprised if you gimp an Ivysaur rather than outright KO her with a kill move, because it happens very often.
-While she does have kill moves, they do have some startup time. Keep yourself spaced away from these moves.
Do you feel the opponent can shut down aspects of Lucario's game?
-Not particularly, just know that her bair is her main spacing tool.
-Be aware of her tether recovery. Retethering to the edge can lead into mindgames.
-Her tether has a DECEPTIVE amount of range. Be careful when trying to do a speed edgehog.
Counterpicks? What to avoid and what to enforce?
-Her main weakness is her recovery ability, so if a stage doesn't have tether-able edges, then it will put her at an automatic disadvantage. Avoid stages with no pits.
CHARIZARD (aka Bowser 2.0)
What moves or tactics should we watch out for?
-Utilt: A decent move for poking through platforms
-Dtilt: A really good poke move. It comes out fast, has very good range, and has very little ending lag.
-Fsmash: It has a lot of startup and ending lag, but it has a lot of knockback. One of his primary killmoves.
-Fair: A decent edgeguard and KO move that has weird properties. Charizard must hit you close with it in order to produce knockback. Otherwise, you will take damage but knockback.
-Uair: A decent juggle move, but it only has one hitbox and is not a sexkick despite its appearance of being one.
-Bair: Another decent KO move that must be sweetspotted in order to produce maximum effect. If you are set on fire, you were with the sweetspot.
-Dair: A spike move that has a small amount of startup time.
-Flamethrower: Basically the same as Bowser's fire breath, but with slightly more range, I think. Aura Sphere can cut through it.
-Rock Smash: This move has some different properties to it. You can either a) get hit and take a large amount of knockback or b) get hit and take a lot of damage, but not a lot of knockback. It has a good amount of shieldstun and can eat shields if used repeatedly.
-Fly: Charizard's recovery move. It has decent KO power at high percents, and also has Super Armor during the rising motion. It's very difficult to interrupt the move once it has been started.
Glide: Charizard can glide, but it is undoubtedly the worst one in the game because of its startup time. He can also Glide Attack, but once again, it's probably the worst one.
Dthrow: A possible KO move at higher percents, but it's weaker than Squirtle's IMO.
MISC: Big and heavy. Dash is faster than his walk. Has multiple jumps.
What moves or tactics should we try to enforce in this match up?
-Charizard has no projectiles or reflector, so feel free to use AS. He is a big target for AS.
-In terms of range, Charizard can challenge you with some of Lucario's moves. However, his moves are slower overall, so take full advantage of Lucario's lingering hitboxes.
-Force Palm chaingrab...you can use it but beware of attempts to escape it.
Do you feel Lucario has an advantage in any particular scenario of this matchup?
-Lucario probably wins in the aerial game, but Charizard can keep up with Lucario on the ground. Just watch out for those RAR bairs!
-Since Charizard is big and heavy, you can combo him somewhat easily.
Do you feel the opponent can shut down aspects of Lucario's game?
-Charizard is a "power" character, so his move will certainly do more damage than Lucario's early in the match. Be careful about getting KO'd early before taking advantage of Aura buffs.
-Don't be surprised if Charizard lives a long time if you don't have Aura.
Counterpicks? What to avoid and what to enforce?
Once again, I don't exactly know what to avoid or CP.
OVERALL: Most PTs know how to play at least one Pokemon very well, some learn two. It's very rare you'll find someone who is good with all three, so expect Squirtle to be one of their best. Squirtle is also probably the one that gives Lucario the most trouble. Charizard can give some trouble, but it can go either way. Ivysaur will probably give the least amount of trouble, but do not underestimate her. As a whole, I would say the matchup is somewhere near the NEUTRAL to borderline ADVANTAGE area depending on which Pokemon your opponent uses the most.
