Nullpointer Exception in Azorius deck

Hello Sirs,
I have an Azorius deck I've been trying to play in constructed mode Other decks work, just this one giving me problems. There must be a specific card triggering this issue. Note that this usually happens somewhere during the first turn.
Here is the decklist, maybe there is something problematic here?
2 Angel of Serenity
4 Azorius Charm
4 Azorius Guildgate
4 Condemn
4 Court Hussar
2 Faith's Fetters
4 Hallowed Fountain
8 Island
8 Plains
4 Remand
4 Render Silent
4 Sphinx's Revelation
4 Supreme Verdict
4 Windreaver
Here is the bug log:
