Summary

The main goal of the deck is to find a recursion creature (i.e. Trusty Packbeast), a sacrifice outlet (i.e. Blasting Station), and a free to cast artifact/creature (i.e. Stonecoil Serpent).  Those combo pieces plus Teshar, Ancestor's Apostle on the battlefield allow for infinite loops.  The loop is getting a recursion creature into the graveyard then casting a free artifact spell; this will trigger Teshar's ability, which allows for a 3 CMC or less creature to be put onto the battlefield from the graveyard.  Then depending on the recursion creature and sacrifice outlet you will either sacrifice the free artifact while Teshar's ability is on the stack or after it resolves.  The recursion creature's ability will allow you to get the free to cast artifact back to cast again.  Once the free artifact is cast again the loop is repeated.  More on the loops down in the Infinite Loops section.

Artifact Loops

Artifact infinite loops involve a sacrifice outlet that designates the sacrificing of an artifact.

The great thing about the artifact loops is that you can utilize either a Free Cast Artifact Creature or a Free Cast Artifact.

The downside is that you are more limited on the Recursion options that can be utilized.

Recursion	Outlet
Junk Diver	Arcbound Ravager
Myr Retriever	Thermal Navigator
Salvager of Ruin	Grinding Station
Workshop Assistant	Krark-Clan Ironworks

Note: There are 0 cost mana rocks listed in the Free Cast Artifacts list.  The infinite loops that can be performed with those cards will yield infinite mana loops to combine with Walking Ballista as a win condition.

Creature Loops

Creature infinite loops involve a sacrifice outlet that designates the sacrificing of a creature.

The great thing about the creature infinite loops is that you can utilize any of the Recursion options available as they're all creatures.

The downsides are that the Outlets are smaller in quantity, you can't loop with the Free Cast Artifacts list above, and you have to use Free Cast Artifact Creatures.

Recursion	Outlet
Junk Diver	Altar of Dementia
Myr Retriever	Blasting Station
Salvager of Ruin
Workshop Assistant
Kor Skyfisher
Trusty Packbeast

Protect Your Combo

Setup your protection spells and your mana for the right opportunity to align your combo.  Pay attention to the mana available to your opponents.  Try to get Grand Abolisher on your field, activate Ranger-Captain of Eos or cast Silence during your turn so you can't be interacted with.

There's also a tech you can do while Teshar, Ancestor's Apostle, Shimmer Myr and Ranger-Captain of Eos are available to force instant interaction during your opponent's upkeeps.  First make sure Ranger-Captain of Eos is avaialble from your graveyard and also that Shimmer Myr is in play during an opponet's upkeep. Cast an artifact, return Ranger-Captain of Eos to the battlefield with Teshar's ability and then with the tutor go find a 0 or 1 cost artifact creature.  This will reload you with a free artifact spell.  During the upkeep you can sacrifice Ranger-Captain of Eos with its other ability to prevent your opponent from playing non-creature spells.  You can do this during every upkeep for as many artifact creatures as you can tutor out.

One very important tool to remember is using the Glasses of Urza, it's not the same kind of protection as the other cards.  This is how you get information on when to try and play your combo based on what your opponents have in their hands.  You can also do something similar with an Urza's Bauble loop, be sure to keep in mind that you might lose to over drawing when using a Mishra's Bauble or Urza's Bauble loop.  When looping Urza's Bauble poke at your opponent's hands that you think might have draw effects that could impact you.  Stop the Bauble loop at an amount of cards you think is safe.  As you learn more information about your opponents hands with each loop or if you know the deck lists you might be just fine looping into the remaining cards in your library.

Gameplay

The goal is to build your machine.  If you can build your machine you win, if your opponents are able to prevent you from building your machine you lose.  A good opening hand will consist of a ramp card and an advantage card.  You really are looking for a self mill option that can be played on turn 1 or turn 2.  So you'll want to mulligan down to 4 at most with your opening hand.

It is entirely possible to win on turn 1 with this deck.  With an empty board the required mana to cast the cheapest pieces to complete the combo is 8 mana (Teshar, Ancestor's Apostle, Myr Retriever, Grinding Station or Altar of Dementia, and a free to cast card).  The most mana you can get with 8 cards (7 + 1 draw) is Jeweled Lotus, Ancient Tomb or Crystal Vein, Mana Crypt, Mana Vault, and Sol Ring or Lotus Petal. Those five cards would add up to 10 mana.  The remaining 3 cards would have to be your combo pieces.  As you might notice you could potentially mulligan down to 7 and still have a turn 1 win if the stars aligned.

In all likelihood though, you won't be winning turn 1. Therefore you'll want to focus on advantage cards and your cards to disrupt your opponent's while you try to gather your combo pieces.  While you're trying to gather your combo pieces your main job is to pay attention to your opponent's and try to look for an opportunity to combo off after they've used their interaction.  Be especially aware of opportunities to get the Urza's Bauble loop or Glasses of Urza, you'll want that information about when to try and go off with your combo. While moving through your deck be sure to look for the protection cards noted above too.  Once you have your combo pieces, look for the right oppotunity to build your machine, whether its a time machine, a world peace machine, or something else entirely.  Then win the game.
