One of many frontier ensoul lists running around.
Ensoul Artifact: The engine of the deck. Not much explanation is really needed.
Tezzeret's Touch: More copies of ensoul. The extra black generally doesn't justify the recursion effect here, but it makes draws that aren't ensoul less embarrasing.
Shrapnel Blast: Provides reach, as well as killing creatures like Seige Rino.
Ornithopter: An ensoul target, can easily come down on one to start beating with a 5/5 flyer on turn 2.
Bomat Courier: Another turn 1 ensoul target, which can draw cards and is hasty in case it comes down later.
Sumggler's Copter: Slower target for ensoul. It can only really be crewed by Bomat Courier, but can be animated with ensoul to become 5/5 looter.
Hangarback Walker: Decent ensoul target that can get bigger, but it's really for throwing at your opponents with Shrapnel Blast.
Temur Battle Rage: If this deck has a creature that's swinging, it probably has power 4 or greater, letting this push damage through blockers.
Unlicensed Disintegration
: The second clause almost always triggers on this, letting us clear blockers and end problematic threats. In this deck, it's an easier to cast murder with upside.
Tezzeret the Schemer: His +1 gives ensoul targets and helps ramp for explosive turns, and his -2 is both pump on our creatures and removal on enemy creatures. His ult lets us ensoul every turn, although this is unlikely to happen very often.
Jace, Vryn's Prodigy
: All around awesome, giving protection and spell recursion.
