Blue Jump - Rank 10 to God
Edit: God rank again, on patch day: https://imgur.com/a/FvcWK
This deck aims to establish lands close to your opponent's orb and wells, then aggressively pressure their life total. Depending on your hand, you typically build lands straight down the middle, but if your hand is a bit slower, it's fine to go down the side.
Mulligan aggressively for Prophet of Tides, Water Elemental or Oversky Towship, If you have one of those, keep Triton Warrior or Mystic Beast. If you have both of those, keep Frogify or The Emperor's Command.
Edit: Made a slight change, -1 Ninja Toad, +1 Campfire. 3x Ninja Toad could sometimes get cloggy, and the Campfire helps with value trades in the early game. I went with Campfire over Falcon Dive since Campfire can technically hit your opponent's Orb ;)
