I’ve started exploring using Double’s dash as an assist and it seems like it could be a viable option for alpha counters. Her dash covers a large space, has an invulnerable period, and it can cross up.
Aside from letting you avoid chip, it lets you punish things that wouldn’t normally be punishable with proper timing. I know that you can catch valentine’s knives from full screen and Argus Agony on block from midscreen-ish. I think you might be able to catch Parasoul’s level 3 and Argus Agony from quite a bit away by dashing twice, but the lacking training mode makes testing this difficult.
It’s also a useful tool for getting in on projectiles in general and seems to be able to punish Peacock’s 236HP (though it won’t save you from the plethora of other shit she no doubt already has on the field). A recording feature would be a godsend right now.
