You can't be lazy if you want to learn Tremor, so I would suggest you go the combo thread and practice, practice, practice. Especially his db2u and db2d can be tedious in comobs for beginners. Also you need to learn the db1dd cancel. it makes every combo safe. Another thing which is also nice to have is the ex db2 run cancel. It gives you an armor and you can proceed into combo. Also 13% OTG is only guaranteed after a small delay in a hard knockdown like db2 (except for lava skin in metallic), f2, 33, and db1 in Aftershock and variationless. Those would be the universal tips for Tremor so far.
What goes for Aftershock, you will use the dd1 while in air a lot as an anti-zoning tool and to keep your opponents at a distance.
