Equivalents to Blacklance Paragon (black, flash, combat trick, deathtouch):
1. Gifted Aetherborn (deathtouch, lifelink, though no flash or combat trick)
2. Ambush Viper (green, but closest flash deathtouch, not black)
3. Murderous Rider (black, lifelink, removal, strong for mid-combat tricks)
4. Nocturnal Feeder (black, deathtouch, not flash, but dies for effect)

Closest black options with flash and deathtouch are very limited; Blacklance Paragon is unique in this specific combo for black. Murderous Rider is often functionally similar as a surprise removal/lifelink beater.
