Aggressive and resilient deck based around maximising the utility of the Ozolith to recover from removal and boardwipes.
Ozolith saves counters from Steel Overseer, Stonecoil Serpent, Animating Faerie and Crystalline Giant.
Crystalline Giant (mechagodzilla) keyword tokens are saved by the Ozolith as well, so you can get Hexproof/Deathtouch/First Strike/Trample/Flying/Vigilance as well as loads of +1/+1 counters. You can also animate the Ozolith with animating faerie to recover immediately from removal.
Emry lends resilience and a bit of filtering to the deck. Often you can grind out games by bringing back artifacts and she almost always costs one mana in this deck.
Karn's Bastion allows you to proliferate at instant speed. It's an on board trick but it's powerful and people seem to miss it a lot.
Barely even a single colour, and all early plays are colourless so mana is extremely reliable.
Good Matchups:
*Jeskai Cycling - Soul Guide Lantern and Scrabbling claws eating your opponents graveyard make the game very one sided since they can never zenith flare and you can bog the game down easily with your bigger creatures.
Winota Midrange_ - presideboarding your creatures are bigger, they have limited removal and you can unsummon/tales end the Winota. If they can't play that then their deck does nothing. Postsideboarding the deck has four copies of Grafdigger's Cage so they really can't do much to damage you whilst you build up overwhelming board presence with Emry, Crystalline Giant and Steel Overseer.
Even Matchups
_Yorion Luka - Stone Coil Serpent dodges Teferi and all of their removal except Shatter the Skies. Tales End is brutal against Yorion blinking all their permanents. With Ozolith and Animating Faerie recovering from removal is fast. You can cancel out the Agent of Treachery/Luke combo by either unsummoning the sacrifice target or using Tales End on the Agent trigger. Game feels even.
Bad Matchups:
*R/B Witches Over/Cat Combo sacrifice. If they get their Priest of Forgotten Gods out early with creatures to sacrifice for it, it becomes very difficult to maintain a board presence. Our creatures are also especially vulnerable to Claim the Firstborn. It is possible to keep them off balance with Tales End and Unsummon and win attritionally with Emry but you need to be both lucky and play well. Grafdigger's Cage makes sideboarded games easier but the main threat here is claim the firstborn and a sacrifice outlet.
