This has so many subplots its make me shout out in happiness. I love plural plots and confusing revelations, so it's all good.

The Alice deck was meh for me. As soon as you saw alice, you automatically knew the whole duel. So that was bit of a turn-off for me.

The last paragraph intruiged me, though. Kreszentia is a machine or some created by Von Dijkhuizen, similiar to Kurotsuchi Mayuri and his apprentice in Bleach.

Keep this up, I really really like it.
