A tick throw is half the mix up. It’s good to start with tick throws and have frame traps ready in place of the second hit. You want to get your opponent used to something then you switch it up.
Example: I main Bison so if I’m close enough I jab then grab (tick throw) simple right?
Now my opponent has to preemptively hit grab to break it. Now next time I’m in their face I jab then I do cr.mp. That leaves enough frames for their throw to start up. That’s just a basic one. Some characters have really nasty mix ups. Overheads and lows are mix ups but most people can react to an overhead. You wanna mix up overheads on meaty wake ups to make them safe. Also opens up combo possibility. Also having certain attack patterns can be predictable. Mix up when you wanna dash in or jump or wiff a move. Idk who your main is but YouTube mix ups, resets and set play for your character.
