Help with Tiamat deck

[Footbeat]

After a couple years of Kitchen table magic I finally got into arena with afr and tried my hand at a Tiamat deck it’s pretty jank but still pretty fun and I win a decent amount any help would be greatly appreciated here’s the deck list https://deckstats.net/decks/187338/2182722-tiamat?lng=en it’s kind of in a treasure shell which I love as it fits the theme and let’s me cast Tiamat without a bunch of mana fiddling

Not sure how many wildcards you have, but HelloGoodGame just put out a video for a Tiamat deck today on YouTube. I've copied his decks before and they're at least fun to play.

Here's a link to the decklist:
