MTG Salvation

I have purchased the Breya package as my second Commander deck, and am looking for advice on how to update it. I am willing to spend money on upgrades, but would prefer not to break the bank. The tricky part is that I want to use my decks to introduce others to the format, in addition to playing them myself. This means Breya should aim to have as close to a 50/50 match-up with my current deck (Teneb) as possible. My Teneb list can be found here:
http://tappedout.net/mtg-decks/15-11-16-teneb/

My rough goals for Breya are:
* The two main themes are value recursion and infinite combos
* Fine to play in 4-player games, but also fine dueling with my Teneb deck
* Can grind out wins in the late game with value recursion
* Able to combo-kill quickly but not streamlined solely to do this every game

My preliminary ideas are to cut:

• 1x Akiri, Line-Slinger
  
• 1x Armory Automaton
  
• 1x Magus of the Will
  
• 1x Bruse Tarl, Boorish Herder
  
• 1x Sanctum Gargoyle
  
• 1x Jor Kadeen, the Prevailer
  
• 1x Godo, Bandit Warlord
  
• 1x Hellkite Tyrant
  
• 1x Hellkite Igniter
  
• 1x Filigree Angel
  
• 1x Whipflare
  
• 1x Grip of Phyresis
  
• 1x Parting Thoughts
  
• 1x Ancient Excavation
  
• 1x Migratory Route
  
• 1x Grave Upheaval
  
• 1x Cranial Plating
  
• 1x Fellwar Stone
  
• 1x Loxodon Warhammer
  
• 1x Bonehoard
  
• 1x Nevinyrral's Disk
  
• 1x Blinkmoth Urn
  
• 1x Curse of Vengeance
  
• 1x Trial // Error

I am leaning towards adding:

• 1x Time Sieve
  
• 1x Goblin Welder
  
• 1x Lightning Greaves
  
• 1x Nim Deathmantle
  
• 1x Kuldotha Forgemaster
  
• 1x Duplicant
  
• 1x Krark-Clan Ironworks
  
• 1x Ashnod's Altar
  
• 1x Fabricate
  
• 1x Thirst for Knowledge
  
• 1x Scrap Mastery
  
• 1x Deadeye Navigator
  
• 1x Scourglass
  
• 1x Inventor's Fair
  
• 1x Dreamstone Hedron
  
• 1x Mind Stone
