Hi, I was today in Legacy event in Vienna. 2-2. 66% was U+something... It was horrible for me. My current decklist is really not prepared against blue-based decks.
Match 1 RUG 0-2
Match 2 bye
Match 3 UWb Miracles 0-2 killed by Jace. He counter or Vindicate all my key cards...
Match 4 ANT 2-0 (in game 2 I survive Tendrils for 20, thanks to Lightning Helix and later I killed him with another Helix when he Ad Nauseam to 3lifes in response via Scroll Rack).

So as said many times, deck is very good now against aggro and combo, but blue-based control is always loose.
Main issue is win condition. Even when get ''board control'' I have issue how to kill him...

I have to change my decklist radical. I think I will switch back to mono-white although lifegain was very good...
Than I think to remove Noxious Revival. I will add more Sensei, and I need another good win condition (maybe RIP+Helm, ...)
I'm thinking again abaout Mishra's Factory, Wasteland and maybe Crucible of Worlds
