Maybe I'm just lucky. This brew has been destroying the Bo1 queue. At the very least, it's got a good shot against any of the meta decks. It's got enough lifegain to beat RDW and WW variants, and the negates give you a shot against the various control or midrange walker decks since you've got plenty of early beats to put pressure on them and you can generate a ton of card advantage against control via your own Vivien and Growth Chamber Guardians and of course Krasis, so you've got reach. The Negates aren't dead against any decks, they're fine against any of the 3 and 4 mana enchantments that WW plays and I'm not going to complain about Negating a Risk Factor or Experimental Frenzy.
The matchup vs Drakes is a little rough, but Vivien amd Krasis helps. I've won games by jump-blocking drakes with Hadana's Climb.
