Here are some basic ones to remember:
(Mid Screen) Cross-up :snka:/:snkb:, land, stand :snka:/:d: + :snkb:, :d: + :snkc:, :qcf: + :snkd:/:qcf:x2 + :snkb:/:snkd:.
(Mid Screen) Jump in :snka:, :snkc:, land, dash in quickly, stand :snka:, :d: + :snkc:, :qcf: + :snkd:/:qcf:x2 + :snkb:/snkd:.
(Mid Screen) While opponent gets up do a meaty stand :snkb:, when it hits, :d: + :snkc:, :qcf: + :snkd:/:qcf:x2 + :snkb:/:snkd:. This combos if you time the meaty stand :snkb: just right.
(Mid Screen) Cross-up :snka:/:snkb:, land, close stand :snkd: (1st hit), feint cancel with :d: + :snka: + :snkc: as it hits, dash in quickly after the feint cancel, stand :snka:, :d: + :snkc:, :qcf: + :snkd:/:qcf:x2 + :snkb:/:snkd:. Once you feint cancel quickly dash in to be able to be close enough to combo the stand :snka:, :d: + :snkc: link.
(Mid Screen) Cross-up :snka:/:snkb:, land, :d: + :snkc:, :qcf:x2 + :snka:, before they hit the ground from falling do :qcf:x2 + :snkb:.
(Corner) Jump in :snka:, :snkc:, land, walk in a bit, close (stand :snkd: (1st hit), feint cancel with :d: + :snka: + :snkc:, quickly dash in)xn, :d: + :snkc:, :qcf:x2 + :snkb:/:snkd:. If your timing is good you can continue the feint cancel loop for a couple of reps.
(Corner) Jump in :snka:, :snkc:, land, stand :snka:, charge :d:, then :u: + :snkd:, break it (:snka: + :snkb:), then do :qcf:x2 + :snka:, before they hit the ground from falling do :qcf:x2 + :snkb:. You can also do his :qcf:x2 + :snkc: super then hold the :snkc: before they hit the ground to follow it up with an extra hit of damage.
Enjoy.
