Take advantage of the input buffer.
Mortal Kombat is the best example of input buffer. Essentially, Nether Realm uses a queue system for their combos, which means you can press the inputs for a combo as quickly as you can, and as long as you press each button once, the moves will come out. In King of Fighters XV, that occurs when canceling moves. One quarter-roll can activate two moves if they cancel into each other, for example.
