Well take a look at the new cards, exclusive products, and a twist on tournament play that might just land you a shiny new promo card
Its difficult to upgrade since you have to adhere to such a restrictive color identity, but its exceptionally easy to scrap for parts since every card can technically go in any other deck
There are a lot of cards in the build though that trigger on upkeep Orzhov Advokist, Aven Mimeomancer, Evolutionary Escalation, Sheltering Ancient, Sporogenesis, Crescendo of War, Kumena's Awakening, Phyrexian Swarmlord, and of course the commander Kros, Defense Contractor so I think it will be really strong
Bonus points if you already use cheap artifacts that arent doing much after they hit the board
