hmm... yeah... this is correct.... but... even so.... one free hit on a pokemon isn't necessarily a huge thing... I agree... it's not a good thing... but it's not really grounds for being considered an advantageous matchup on its own.
Depends on the percents, but in general, I'd say it's better to clear your opponent away, give yourself breathing room. It's a little more difficult at low stamina, but not TOO significantly so.
But given an otherwise dead even match-up, pretty much anything is enough to give a 5% advantage, turning it into a 45-55%, and this is something.
the fact that the match up is even with just ivy and char.
And using squirtle makes it a disadvantage, and if you don't use squirtle it's a disadvantage because you make yourself vulnerable.
Your never forced to use zelda or sheik and such any position your in is of your own agenda.
Squirtle coming out is an ill effect that forces a switch most of the time, if a switch must be forced than your at a disadvantage anyways because Yoshi has just controller one aspect of your game, in a way the Yoshi player is now controlling part of the match at the point charizard dies or is about to die.
At that moment Yoshi can look at you and say "What are you going to do, because regardless Im in a good position and You are not" thats a disadvantage, if 2 out of 3 is neutral 3 is a disadvantage but 3 can be avoided by giving your opponent control or momentum of the match for that moment than you have given Yoshi something that is not neutral, you have given him control unwillingly.
Sorry for adding when I said I'd be quiet =P
True, but realistically speaking, there are enough techniques to avoid the fall-out that it's not a major disadvantage.
If you spawn as squirtle, it basically doesn't hurt you.
If you're forced to switch due to stamina, then you can do it safely, but you need to clear your opponent first, get them far enough away, that they need more then the transformation time to get back.
So, it's really not bad, not enough to justify any more then a 5% advantage for Yoshi.
