First, start off with Headbutt. This attack has increased hitsun, allowing you to true combo into Headbutt. Now, because of this move's extra hitsun, you should have enough time to combo into Headbutt. After that, for a true combo, follow up with Headbutt. Next, take advantage of the high hitstun of Headbutt, and perform a Headbutt. Finally, finish the combo with Headbutt. After finishing the combo, continue the combo with Headbutt. And if you did everything correctly, you should be able to use that move's massive hitstun for a finisher. In this case, DOSKOI!, that's an acronym that means Headbutt.
