I can do the forward throw infinite on the lighter characters pretty easily,but heavier ones,ehh,not really.Most of the time i do the footstool infinite. Sometimes i will also do the iceblock lock, but i didnt last tournament. There are SOOOO many combinations of throws and crap with IC's,lol. What's funny is,ive pretty much spent most of my time actually training with 1 climber,i would recommend you do that to. Idk if you saw it but during my match i held out quite a long time against Ike as one climber,my training payed off haha.It's just Nana's AI is DEFINITELY not trustworthy and you will need a backup plan when she dies.
