well, i usually use 66B BE for combos and 22_88B BE as a whiff punish, i say this because like i said against solid players, you cant just put it out there other than a whiff punish imo because they will block it, JG the second hit and punish you in a BT'd state, i agree about the 60pts of life remaining area, but then again, what does she have so threatening to make them duck anyways if they can break throws?...
...you can see SS coming out, and CS is kinda easy if your looking for any throw attempt from its animation... its more of a 50/50 guess for you AND the opponent in that scenario, you attempt a throw they duck and punish or you do 22_88B BE(and if its blocked by a solid player) it will be JG'd into free damage leaving you being punished in a BT'd state or GI'd into a free post GI guessing game...those players know to stand block and react accordingly in that spot, to me its way too much of an uphill battle for Ivy, and making it more strenuous for the Ivy player in return.
additionally, B~K isn't that great on normal hit in that scenario because she has no advantage outside of defensive response i.e JG/ GI attempt or block and punish attempt or maybe step a slow linear attack into whiff punish and that's all she really has in that spot again making it easy for that solid player to know whats up... this is all coming from an offline pov...online however i think what your saying is quite viable...the thing is you have to be VERY tricky with her for that to be viable offline and not so much online, and that can cost her too if your instincts/reactions with her aren't on point.
Also i wanted to add about the latest vids from EVO from Link and Kinetic, from one Ivy player to another from what i saw you guys both have your own unique "ways" of playing... but if you guys combined both of your styles of play together it would make for a very scary Ivy indeed, unfortunately since you guys play completely different styles/ways with her, it makes it too easy for good solid players to catch on a capitalize on you abilities, if you guys can combine the two styles of play together, you def(imo) would have done much better in placing higher in the long run... if you can put personal match nerves or whatever aside and be open to everything she can do/accomplish... just giving my honest thoughts/opinion from a fellow Ivy player on the matches that were available for viewing.
