ugh you're making me miss my mono blue reservoir lol but if i may make a suggestion or two cut a statuary for a
whir of invention just a one of should be fine then cut the two metalspinners and mainboard 2 efficient constructions as an alternate win condition and im sure those dispells are supposed to be spell pierces right and finally take out the reservoir and final
efficient construction out of your side those are just win more slots and add 2 rivers
rebuke you'll find that works well against enchantment based removal and token strategies but everything else looks like how mono blue reservoir should look sorry if all that seemed too preachy i've just been playing reservoir since before rotation and i really like how you made it work though one card i found was the all-star of the deck before was
merchant's dockhand it basically makes the deck fizzle proof but i'd also like to get some advice myself i just built U/W reservoir
