1st CEDH Deck - Considering Urza, Lord High Artificer or Yuriko, the Tiger's Shadow

Hey everyone,

I'm considering going to the commander night at one of my local shops. Apparently they are pretty strictly into CEDH, but I've never played there before. The good news is that they are 100% proxy friendly. They do seem to play multiplayer.

I'm considering playing one of these two decks, but I'm open to changing.

Urza, Lord High Artificer: https://topdeck.gg/deck/big-guava-gamers-presents-misplays-and-mistletoes-feat/ezfjF5cNPTPs3uZByda5OHSdCMg1

Yuriko, the Tiger's Shadow: https://topdeck.gg/deck/1-path-to-exile-cedh-tournament-european-qualifier/VVmovbr8EqPsmZ4DOsyZLNqvZQy2

In other formats I tend to like like Faerie-type decks that can protect themselves and progress their game at the same time. Its ok if its just "stop other people until you win out of nowhere".

My main questions are:

1. Do both of these decks seem like they can play in a competitive environment?

2. Is there anything that is obviously missing or should obviously be taken out of either of these decks?

3. Is there another deck that you think would better fit my playstyle (while still being competitive)?

Thanks in advance, I appreciate it!
