My budget standard deck I threw together for my LCS Standard nights, wanted to try to see how well Aetherborn Tribal would work.
Weaponcraft Enthusiast
He is in here because I can get 3 blockers for 3, or with Mimics and Entourage out a 3/4 or 4/5 for 3 pretty easily, Can also use the Servos to Sac for Yahennis ability
Midnight Entourage
Pumps up other Aetherborn
Gifted Aetherborn
One of the more solid uncommons in the block currently, Lifelink will help keep life total up, and deathtouch makes him a formidable blocker
Fatal Push
removal, very solid removal, and evolving wilds and trigger revolt fairly easily
Metallic Mimic
Picking Aetherborn makes dropping Demon not kill all my creatures with 1-2 out on the field and pumps them up for swinging
Murder
Instant speed removal
Glint-Sleeve Siphoner
Card draw in place of Liliana cause I don't have money for her.
Yahenni's Expertise
Cheat out Yahenni or if looking for a major board wipe with Runious path for free
Syndicate Trafficker
Pump with servos and servo schematic for a big swing plus indestructible in some situations
Demon of Dark Schemes
5/5 Flyer that wipes all the tokens or Smaller cards plus gets energy when you do, and recursion
Servo Schematic
For pumping trafficker, plus could make servos for Westvale abbey
Yahenni, Undying Partisan
Boss of the Deck, with pumps and removal throughout the deck he can get pretty beefy and you can make him indestructible by sacing a Servo from Weaponcraft or really anything else on the field if needed
Westvale Abbey
Sac 5 servos for a big hastey hard to remove demon, usually wins the game there
Evolving Wilds
Triggering Revolt and ramp
Swamp
You kind of need these to play in black... soo yeah
Sideboard options
Lost Legacy
Put in for Jeskai copy cat decks, name one part of the combo and it's stops it in its tracks.
Hope of Ghirapur
Put in for control decks, just slows them down for some breathing room.
The rest are more maybe cards until I find more solid additions and counters to decks.
