If you're talking about his jumping moves, try to get a good read on j.hp, and anti-air with h.dp(m.dp if they're closer)->j.mk->h.sehkmet. Trying to meet him in the air is nearly impossible because of j.hp or blitzer, and horus is too risky because blitzer beats it. If they just spam j.hp or blitzer then a j.light-sehkmet->j.heavy-sekhmet is pretty free. I prefer not to do this, however, because i don't like being vulnerable as sehkmet in general (if it's blocked).
