There's a complex infinite that can be done with Alisa w/Uppercut. Here's how I do it in the most basic form I can put to words

• Launch an opponent to the air with her special
• Combo them in the air with "Light, Medium, Heavy, Summon"
• While the summon suspends them in air, combo them in air with "Light, Medium, Light, Medium" while you land
• Her special meter resets when you hit the ground, allowing you to launch them again with her special
• While they are in the air this time, you only combo them in the air with "Light, Medium, Light, Medium" while you land
• Repeat

This combo is insane but unfortunately, it's an infinite so something has to happen.
