Need help on one card to cut

I have an [[Urza, Chief Artificer]] deck that I love to play, I've been upgrading it over time and it's become quite powerful. I just ordered [[Desynchronization]] for my deck to wipe the board and swing in to close out the game, but I'm not sure what to card to cut from my deck. Any input is welcomed

Here is my deck: https://www.moxfield.com/decks/TGzCRSe1O0SSwJuSxBG_3Q

It is hard to cut artifact creatures, like the Myr, because of my commander's affinity
Thank you!
