[410] cl.HP xx LP Rocket Uppercut, c.MK xx LP Rocket Uppercut, HP Rocket Uppercut - does ridiculous damage, even more if you land a jump in or crossup also if you switch cancel you get both hits of HP Rocket Upper for even more damage!
[564] cl.hp, LP Rocket Uppercut, c.MK xx LP Rocket Uppercut, Super Art - dat damage!
c.LP/c.LK/cr.MP xx Megaton Earthquake - great for pressuring, easy to confirm into switch cancel for damage without much scaling.
LP Rocket Uppercut, LP Rocket Uppercut, Raw Launcher

st.LK ~ MP > MP - this sequence is safe on block and probably the easiest to confirm
c.LP/c.LK ~ s.MP - this is punishable up close, requires correct spacing
