Just a side note, Star Shooting one IC into the other generally works well in this match-up. Their neutral B is also great for Kirby to use against them. Separating them is the key to winning this match-up, If you can not do that then winning will be difficult.
Starshot is pretty good in this matchup. Kirby DOES have invincibility frames at some point while he's Inhaling one character, and the Starshot does nice damage to both. However, you can get punished after the Inhale/before the Starshot by the other IC, so be careful.
Copying the Iceblock is next to useless, unfortunately. I just like to do it because Kirby with the hood looks so cute =3
This has some value. Should a Kirby player master the Infinite Double-Jump Restoration techniue by using B-Airs, then this comment would have some merit; however, not many Kirby players know how to do this, and risked getting Shield->DashGrabbed upon landing.
I just yesterday learned how to do it with Bowser's Side B...it took almost no practice at all.
Now I'm wondering how to do it with Bair, or with any other move in the game. I really have no idea, and I've practiced it with Kirby before, and with other moves, to no success.
And yes, Vulcan Jab IS great in this matchup. It comes out quickly and gets them off of you. Just be careful not to have it powershielded, because then they can grab you, and that sucks.
Dtilt is pretty good in this matchup.
Some Ice Climbers (or at least Bunny) like to return to the stage with Side B...if you can predict this, the easiest way to punish it is with Final Cutter. It's pretty hard to punish otherwise, because it has hitboxes all over. She also tended to not spam the B button, so that the ICs would just fall down to the stage like that, and I fell for it a lot. Again, Final Cutter is pretty good for this, or if you can shield the whole thing, a grab can punish.
As for Nana's Upsmash beating Upthrow...the point of Upthrow being so good is that Kirby lands on platforms that are above you. This is why Upthrow is so good on stages like Battlefield, Brinstar, Smashville, Yoshi's Island, Delfino, etc.
And stages...ban Final Destination, unless the IC you are about to face is notorious for counterpicking some other stage. And although you may think this is my personal bias, pick Brinstar or Norfair against Ice Climbers. The matchup immediately tips largely in Kirby's favor. And yeah, Rainbow Cruise is good too. In all honesty, if you pick one of those three stages, the Ice Climbers main will most likely switch to another character.
Right Lain? Norfair? Dedede? Teh Spamerer? :D
Good post, IC3R
