Yeah, it does outrange Ivy, but Razor Leaf reflects Ice Shot and goes through it. You'll be fine as long as you don't let yourself get forced into the air. I actually think that Charizard has more trouble with Ice Shot than Ivysaur does - he's slow in the air, huge, and Flamethrower is limited in range and duration, so he can't really block Ice Shot that well. Gliding helps a lot for getting to them, though. Just be careful of Blizzard and tilts.Wouldn't it be common for an IC to use mini glacier attack like first thing especially against someone like PT? not like Ivy can really out range that.
You'd be surprised how effective it is for Squirtle to d-air their shield and land on the other side of it... Even Mario can do that. And yes, Ivysaur can force the Climbers to approach, but what then? If they know about desynching (which they will), their approach becomes amazing, borderline godly. Ivysaur simply can't brickwall two opponents at once - nobody can. Yes, b-air is good, but they will break through it eventually, and a single Squall from them does as much damage as six of Ivy's b-airs, so all you'll have accomplished is wasting time, which is not helpful early in the match.Squirtle is small enough not to get grabbed, yet he is Easy Shield Grab fodder. Charizard is better off later in the fight when against IC, Ivy i recommend because Ivysaur can space well with Bair and send back IC's Projectile with a razor leaf, forcing IC to come and approach.
And again, this isn't about who has the best match-up, it's about who is best for starting. Squirtle will get forced to approach by Ice Shot, and he can do so. He's good at seperating them and gimping Nana early in the fight. Hell, he has potential to gimp Nana, edgeguard Popo and gimp Nana on the next stock before fatigue kicks in. Charizard can get in their face and **** them altogether, being capable of taking their stock and then handing the baton to Squirtle for the next one. Ivysaur is OK, but made obsolete by the other two. He doesn't seperate that well, and gimping Nana is made risky by Popo being able to simply edgehog.
Ivysaur is easily your best option against a lone Climber, and I recommend that you switch to him as soon as you have Popo alone with a low %, but when they're together, you're much better off with either Squirtle or Charizard. And since they start the match together, you'll need someone who can work around that.
