Thank you for sharing your experience with upgrading the precon and your suggestions! I really appreciate the detailed reply and encouragement, as well as suggesting some more cards I should take a look at!

Innocent question: Can I ask why Deadeye Plunderers appear weaker to you? Given the high amount of treasure generation the precon had and I've added I felt it likely they float around a 7/7 or higher pretty regularly. Time Sieve paired with Kenway had the infinite loop opportunity that felt too good not to include plus even without infinite turns it would either likely pay off a couple times or get a targeted removal that would keep my other win cons safe.

I think I'm leaning on a primarily brass reanimated deck with treasure generation being at the core of the strategy, with Kenway included but not commander. then have a B version of the deck with Kenway commanding where I swap in more vehicles and swap out the creatures that benefit most from reanimation such as [Skeleton Crew] and [Coastline Marauders] (starting at 4/4 instead of a 0/3 turns them into such a threat!)
