Upgrading Daretti's win cons

Looking for ideas on making my Daretti deck better. It is more of a fun deck, getting a big field full of artifacts but looking to get it better at closing out games. In recent games this has been a bit tricky: Episode 13, Episode 7.

Episode 5a - Alela, Chainer, Ruric Thar, Estrid

A quick version of the "lost" episode with a audio track.  Let me know how this compares to the regular experience!

Alela, Chainer, Ruric Thar, Estrid are the commanders - who can make the distance?

Episode 15 - Obzedat, Meren, Roon, Ishai and Reyhan

This match sees Obzedat, Meren, Roon, Ishai and Reyhan battle off.

Will this lead to a long-awaited result for Roon, Meren or Ishai/Reyhan? Will Obzedat win on the first attempt?
