Pichu
+Mario has a very good combo game on Pichu not nearly great as he makes it sound pichu acts like fox you can't really attack him right sure you can grab **** him but grabs are very hard to get pichu is nearly totally lag free
+Edgeguarded easily due to slow up B and laggy stuff Pichu has the least lagiest recovery in all of smash and over 160 options to pick from wall jumps, jolts, side-B, and double up-B and etc. pichu is VERY hard to predict most of the time
+Pichu is the worst character in the gameWhat does this have to do with the match-up YL is decent vs peach/puff
+Pichu can't KO worth jack pichu has the storngest f-smash, 6th strogest up-smash with thunder, and great gimps with b-throw/jolt this man is totally nuts
(If you really have to counterpick a Pichu, just go shiek on FD LOL. You shouldn't ever have trouble against a pichu. Just combo it to death cuz its so fat and dumb.) Fun fact i've had people CP me with sheik and their sheik did much worse than their main.
Pikachu
+Chu can be throw-chained how are you going to get a grab?
+Chu has a semi-predictable recovery no
(Counterpick DL to counter the effects of pika's usmash) this is fail advice pikachu can/should always be able to recover you doubled his lifetime and did nothing for your self
Yoshi
(Not sure where to counterpick. DL maybe?)
Bowser
(Counterpick FD or FoD. Combo heavy stages = even easier combos)FoD is great for bowser 2nd best stage for him
Kirby
+Kirby is really light, thus easy to KO
+A character as terrible as Kirby makes inability to combo not matter so much for Mario
+Easy to approach you don't approach kirby you just outcamp him and you win this isn't that great of advice
-Difficult to combo you can
(Counterpick Yoshis for very easy KOs)FoD is way better YS has SD tricks with should be most of your advice not to be ******** and fall for the SDs
Mario
+/- Not much too it, he's the same character...it's a different player which makes it worlds different
DK
(I cant think of any counterpicks)
CF
FD for chainthrow Falcon's best stage and you say take him there???
Purin
+Purin is really light, thus easy to KOH-box
IC's
+When you only are dealing with popo, he is easy rack up percent on, deal with, and combo
-Mario has difficulty seperating IC's, and is consquently prone to infinites, CGs, and combos.
-ICs basically negate Mario's grab game
(I don't know much about this matchup, but uhhhh go with FD lol)
