Shadowverse

I won on the first try. I didn't expect it myself, as I thought the deck was too weak, despite having Olive, two Octrias, a lot of board flood, rush, storms, buffs, and other joys of life. I think I lost the first battle against the Shadow, but then I won the next four almost effortlessly - two portals, Sword, and Blood. In the last one, it was funny; I played like a true aggro deck on turn six - flooding the board and finishing with Celia for 7 damage. So, I recommend this deck for general play.
And yes, I don't mind losing to decks with the New Year's Vanyushka, so I didn't try to specifically counter it.
