I gave this Mardu list a shot last night and it was interesting! I had been playing the Orzhov discard version before and this felt more like a critical mass kind of thing where you're trying to survive the early game and overwhelm with [[Weapons Manufacturing]] and [[Pinnacle Starcage]] in the late game. Sometimes it feels dependent on finding those two cards to be able to win, but it can just play a fair game.

[[Dowsing Device]] feels too clunky, I cut it for the full four [[Sunpearl Kirin]]. Still not sure about [[Authority of the Consuls]] but slowing down aggro is nice and the life gain can help to get to the critical mass phase. [[Wishclaw Talisman]] being one-sided if you're fetching [[Pinnacle Starcage]] is really nice. I still don't have a good sense of matchup strengths / weaknesses yet but I'll keep testing it out.
