In that video we already see a lot of great tools in use:
-that big high horizontal, looking good. It doesn't move her forward, in fact she hangs back a bit after it, making it more difficult to whiff punish.
-FC 1B or whatever input it is now, that player definitely didn't do it on purpose. A+ long range low poke
-SCIV 2A is there, another low that I liked in SCIV
-SCII bA / SCIV 66A, half circular mid poke
-FC 1KK is there for a nice knockdown low
-long range and close range launchers
-while landing long range tracking low, nice little gimmick attack, better than a useless high jumping A
-vanilla mid poke, except it looks like it can be charged? 2:40
-AA and 44A are there, though the range is a little disappointing
-6B+K I think it was in SCIV, the double high punish
-66KKK, strength depends on its CH confirmability and if the second hit can be GI'd
So we have mids, highs, and lows at a lot of different ranges, what's missing? Need to see if she has safe CH damage (out of something like 6A+B_6A+BG CH confirm or something). Her range honestly doesn't look like anything special right now other than that big high horizontal and the good old FC 1B. Other characters' basic attacks and others got range boosts, so staying the same on anything should be concerning for Mina players. However, having a usable long range horizontal and low is a big deal. Maybe it's more interesting that way for her to not have the longest range fast safe mid but to have those tools instead. Staying out of their step catch range and sidestepping and keeping them in your step catch range and poking at them is sure be to be annoying to fight against. Like a horizontal Raphael.
