Saheeli Double Combo Oathbreaker (Oathbreaker)

This is my first approach to the oathbreaker format, saheeli combo.
The deck only runs both of the eldrazi titans as creatures, allowing saheeli to create tokens for any spell you cast.

The deck tries to draw and cycle a lot of cards to create a token army to protect saheeli and to find the key pieces for the victory.
This deck wins in three different ways.

First off, by casting any of the "polymorph" spells on any of the tokens created by saheeli. She can turn any artifact into a copy of kozilek or ulamog, granting them haste in some way thanks to her -2 ability, as you sacrifice the original one and it returns back to your library. You can also cast them right before your turn to attack without sickness.

The second wincon is via Iso/Drama combo. Note that you can perform the combo with only 2 mana artifacts as saheeli will create the third copy for you. You can loop the bolt spells by discarding ulamog/kozilek and drawing infinite cards thanks to the signature spell, as the bolts will come back to your library. You can react at instant speed to any threat to the combo as you will have counters and the blue leyline.
If they get exiled, just create an infinite army with retrofitter foundry or try and smash some faces with tezzeret, the third wincon.

You can cast tezzeret the seeker and ultimate him instantly thanks to karn's bastion, to boost all the tokens created by saheeli to a 5/5, making a huge impact in the board.
