After all the restarts, the generator gave me a Kreg and... that's it :(
In my 3 treasure zones, 0 sea chests and only 1 minion in the center. Dug up the Grail and placed it into Conflux, otherwise I would never have found Dimension Door at all.
The whole game I demoned + the center turned out to be rich in Dragon Fly Hives and Zephyrs. The opponent had a huge stat advantage the entire game, but I was more worried about 500+ mana and 30+ spell power, since I never found a Sphere or a Cloak anywhere.
In the epic finale, I got lucky a couple of times. Opp put on the Black Sphere because he was afraid of my resistance, but it turned out that it worked against him.
Anyone interested can watch the finale in the replay.
Thanks for the game.
