Sekhmet is expensive and doesn’t have especially great stats, and it also has a big drawback. But this card gives the Crimson Order two necessary tools:
1) In a deck lacking tricks and mobility, Flight on a 4 melee strength unit is certainly welcome. It allows the Crimson Order to put pressure on a summoner that was overconfident in this faction’s lack of tricks and took too much damage and/or became too exposed.
2) A common occurrence during Crimson Order games is that because of the Devout Cultist, a lot of magic is generated on both sides. When facing other factions that swarm the board and generate a lot of magic, there can be a surplus of the resource flowing that can be hard to take advantage of. In such matchups Sekhmet provides a use for all that magic and because in those same matchups there tends to be a lot of small units, Sekhmet can feed off of them without ever triggering its drawback.
