I know you don’t really want setups and stuff on this thread but I just thought I would share a good unblockable setup that also helps you to time it correctly and allows you to do more damage.
A lot of people usually do this in the corner, after a few juggle tackles, they cancel into jab aegis and then either dash back and allow opponent to bounce of the aegis and then they push them back underneath with a charge partitioned rh tackle, then knee drop for the unblockable, or they just walk back and do a mk tackle ready for the unblockable. Both ways work but some find it harder to charge partition during a dash and some just find the timing and positioning of the opponent when doing a tackle hard to get them in the right place.
So a good way for an unblockable setup is this as well, do the usual tackles (not too many) and cancel into jab aegis, then when opponent bounces of the aegis reflector, jump towards them and hit them with j.fierce but whilst you are doing this, make sure you are charging down during the jump animation, all the way until he lands, then opponent will bounce off the aegis again (providing that you did not do too many tackles before the aegis) and again jump towards them and hit them with j.fierce and again whilst you are doing this charge down until he lands. Your opponent will have now landed back into the aegis on their feet and you will be able to execute a knee drop because of the charge partitioning from the 2 jumps, and voila, you will have created an unblockable.
