Shadowverse

Storm Haven is overpowered, and there aren't many other viable decks.

I almost beat everyone with Storm Haven, except Uriel gave me trouble (which is understandable, as agro-vampire decks also gave this deck a hard time in the ladder). I lost twice, and they offered me a prebuilt deck. I took the one with Aegis and won immediately. However, I got lucky because the AI didn't draw any Carabossa, and on turn 10, it topdecked Vaan and a Corsair Vampire.
