thats bull shit, your not going to wait out each of them for two minutes and its not like they have a problem killing. Also no competitive players would switch pokemon when there that open
So they'd just play with severely weakened pokémon instead, during which time they WOULD have trouble killing or even causing as much damage. In-tournament? Yes, I damn well would wait two minutes (less than that since they lose stamina for every attack they make) to essentially guarantee victory. You underestimate what people will do to win, and an eight-minute match isn't that long anyway. It's the same reason "loop" stages are all banned, as a faster character such as Pit or Fox could easily shoot somebody once and automatically win just by running away from the opponent the rest of the time. Obviously, complete evasion would probably not be possible on a neutral/CP stage but Charizard and Ivysaur aren't exactly great at cornering people either.
Sure Ness and Lucas are fun and could turn out very interesting in tournaments...
Too bad characters like Marth have infinite grabs&pummel on them by simply grabbing and mashing A
Wario's tourney success sure doesn't seem all that swayed by his susceptibility to grab releases and he's even worse off in that regard with his extremely short range and lack of projectiles. (Including but not limited to being infinite grab-released by Yoshi and getting USmashed out of one by Dedede.) DK is infinite DThrowed by Dedede. Yet, these characters are still enjoying plenty of success in tournaments. Who's to say Ness and Lucas can't enjoy the same, Lucas especially? (While I'm not going to explain why I think he's a better character overall, he avoids more grab release follow-ups than Ness does.)
Yoshi has a grab release to spike on 13 different characters including metaknight (easiest of them all), snake, and falco. Yoshi might have a hard time around Falco, but with this technique Yoshi might actually be favored in all 3 matchups.
While for the sake of Brawl I sure hope Yoshi can be a soft counter to MK, I don't think so. :P Yes, he can chain grab [release] a few characters, but it doesn't change the fact he has the worst standing grab in the game. It's like combining the slow speed of Samus' grab with the short range of Lucas' grab, and that still says nothing of his terrible roll/shield because he has to wait for the egg shell to break before he can retaliate out-of-shield. (Hey, at least Samus has the
longest grab in the game.) Yoshi is otherwise a decent character but he's very bad at performing some of Brawl's most basic defensive techniques.
And PKMN trainer may be bad. But if your opponent forces you to approach, they have options. Ivysaur (not familiar with that much) can Razor leaf and Jab, Squirtle has pretty high priority aerial moves and Charizard has teh PH1R3!!!! I still think he should be lower.
PKMN TRNR can't force anyone to approach, that's the problem. Razor Leaf is relatively slow to spam with mediocre range (i.e. easily avoided or clanked) and both Charizard and Ivysaur have a hard time just chasing down an opponent actively avoiding them or very cautiously spacing. It's not even patient spacing, ala non-projectile characters with range like Marth, but the opponent can gain an advantage by playing flat out keep-away. What choice does PKMN TRNR have but to give chase, putting himself at a disadvantage? He can't wait them out, as eventually his pokémon get fatigued and become much weaker.
