Smash Lord
Ganon actually has the advantage in this match up I believe. You can't shield grab him since his aerial will push you out of grab range, and WDing to grab is easily stopped by his jab and forward tilt. Once he separates you a smart Ganon will kill off Nana so he can grab effectively. The smartest thing to do would be catch him in the air, and make sure he doesn't fire off and aerial before you do.so ganon and c falcon are useless against IC hehe...
so what about fox, falco and sheik? they CAN double stick DI right?
Captain Falcon is becoming a common counter for Ice Climbers now. He is hard to grab because of his speed and his knock back will usually push you out of grab range. Don't try to wave dash to grab because chances are he's already in the air again, or half way across the stage. You'll likely lose Nana once you are seperated just like Ganon. However, once you get that grab in, don't let him go. The only time your safe from Captain Falcon is when he is in your hands.
Fox can get out of the down throw-down air chain throw fairly easy if they know how. Even if they do, chances are you can still catch them at least once. Like Binx said if they break loose twice they won't get caught with it so stop trying.
Falco it is a lot harder to get out of. In my experience it's worth trying more often since it's harder for them to break free.
Shiek, if you are uncomfortable with the down air or down smash, just down throw chain grab. You don't actually need to do anything to assist in it.
Also, if you are chain throwing a good percent of the time, you can just throw them and let them hit the ground. They will likely miss the tech, which means an easy wave dash to down smash. If they do manage to get the tech in, they only have 3 options so wave dash forward then punish the tech with either a regrab, down smash, or forward smash.
