Offense
Platinums offensive game without weapons is obviously subpar and opening people up and controlling space will obviously be considerably more difficult. That is not to say that she’s hopeless without items however.
Your 5A, 5B, 2B, 5C, 6B are all tools to use as far as normals go. 5A and 5C are all just cancellable, which means you have access to TK Swallow Moon if you get respect from your opponents.
5B is long and chains into 3C for little confirms at close to max range.
2B is a mid-ranged low that can low profile some moves.
6B is your overhead, done from a certain range gives good frame advantage and the ability to combo.
As far as items go, every single one of your items sans Bat can be used as an offensive tool. Pan is an instant overhead with J.D, Hammer guard crushes, Cat Hammer is a very long and fast overhead, Missiles and Bombs give you chances to go in and presents can be used to control space and movement options.
Defense
Platinum shrivels when it comes down to defensive options. Her options are as follows
Happy Magika
Counter-Assault
Bat
That is all.
Happy Magika is a counter that activates against everything but grabs. It has a huge amount of active frames. Problem is that I feel it’s only good when you know your opponent is trying to frametrap you. I don’t reccomend doing this move on wake-up or every whiffing this move in general because you can honestly be killed for it depending on your opponents resources.
Counter Assault is Counter Assault. Gets you outta blockstun for 50 meter and puts things back into neutral if it isn’t baited.
Bat is your limited DP, wallsticks on corner hit and floats on CH midscreen. Unsafe on block at -11. This is your best option, but you have a 1/7 chance to ever get it and you only have 3 at a time. Though, it’s frame 1-11 invuln, so it’s godlike as a reversal.
Neutral
Your neutral will often consist of trying to control whatever space your opponent wants to occupy and trying to score a clean hit to move them to the corner. The tools you want to use will normally change between match-ups.
For example: If you’re fighting Nu, Bubbles may not get as much use as they’d get against anyone with less range behind their attacks.
Against Ragna for example, Bubbles are pretty nice for limiting movement options. Your neutral tools: 2B 5B 3C
Bubbles
Cat Hammer
Bombs/Missiles
Presents
