So that's 8 cards you should definitely keep
These might be specific to the permanent type you sacrificeDisciple of the Vault for artifacts, Hearthhull, the Worldseed for lands, etc., or more general payoffs like Mayhem Devil and Evendo Brushrazer
When I first set out to make a Top Ten Card list, I knew that I had enough range to finish the allied colors, but I wasn't sure there were enough quality opposite enemy cards to count
But perhaps theres a silver lining to that logic
Phasing is better than giving hexproof instantly (Lazotep Plating, Heroic Intervention) or indestructible (Rootborn Defenses, also Heroic Intervention) - which are heavily played
While there were some card choices I didn't really like, the idea of flooding the board with Servo tokens and then winning with an Aristocrats-esque finish with the help of Marionette Master and Zulaport Cutthroat seemed fun
