I'd love her to be a sort of setup/trap zoner, with spells that interact with one another.
For example, let's say she has a capture move of some kind, similar to Firestorm, some kind of ranged capture. Well, landing it raw does some damage and maybe has some frame advantage or something, but it doesn't capture. Not even MB. Then, let's say she has a projectile of some kind. Shooting the projectile leaves a sort of field behind at the point of block, and if the capture lands while the opponent is in that field - and actually landing the projectile causes the field to follow the opponent - they are captured meterless, and she can combo. Additionally, give her additional types of projectile, one could be a pillar that fires down from the top of the screen and leaves some kind of orb or shape or something behind. Like Fates orb, and maybe it has a small aoe field around it as well that has some very minor properties to it, but those properties change or increase if the field left by the more standard projectiles overlap.
You could have situations where you drop a pillar behind them, let's say. Then you fire a projectile or two and they block, leaving a field in front and in bsck. They overlap where the enemy is standing. And maybe the overlap debuff is extra chip damage, then she can teleport in and engage at close range with staggers or frame trap pressure, so the opponent has to block forever and eat increased chip.or try to make sure read to get out, at the risk of being opened up into a string into her capture for a combo.
Just an idea. That's a lot of work and setup involved, but you could maybe end a combo with the pillar, doing less damage, but ending with the first part of the setup, and giving you some distance to get a projectile or two out, and maybe her ranged capture on block, when in one field or another left behind, does extra block stun, so you could throw it out and if they block it while debuffed or in the field (s) she's guaranteed a teleport or something.
Additional ideas:
A VERY fast interactable reflect. Literally only works on interactables but has insane startup to throw them or direct the explosion back at the person who used it.
A projectile capture, collect and return. She can catch and hold up to three projectiles of any kind, and when she uses the return version of the move it throws however many she's kept back at the enemy, with some debuff to thier damage and such. Meterburning sends them out more slowly.
A mirror image move. She sort of phases into a shadow state and appears above, in front or behind the opponent, which depends on version of the move used (like db1, db1b, db1f), when you do the move you input a single normal that will happen when the mirror images appear, carried out by the image who's input you used meterburning the move teleports her into her clone. So if you did, say, db1u (very small pause) 2, she would appear above them and hit them with a J2. If you meterburn the move she teleports into the clone snd you can continue npressure.as if you had landed a J2 the old fashion was. Additionally, meterburning the move st it's start causes all three images to appear at the same time, but the real one and the one she can spend another bar to tele in to, is still whatever input you originally used. Single inputs only though, no strings. Air version should probably be a mid.
I don't know anything about her lore, and have no idea how appropriate all that is lore-wise, just some ideas that could lead to super deep and interesting gameplay for the enchantress player, as well as the person playing against her.
