Dude, I thought Ice-Climbers were a Dedede's counter. They are his worst match up, since they can't be chain grabbed, and their desynched moves are good for building damage on him, plus they can chain him as well, and they have great knock out moves.
But I will try to pride myself on use of the Forward Smash, if you validate it so much in this match up. And you're sure Back-Throw is my best way to seperate them? Any specific aerials that help me out here? They seem to outprioritize my down-aerial... Ah. You say to not rely on them too much period. I guess my best bet is to simply try and seperate them but try not to let them stay synched.
Thanks for the advice. I'll talk to ya later! Ima take a bit of a break to hang out with my brother, then I'll be on again.
