How does the Prince fit into this deck? Is it worth crafting him for this deck?

I specifically crafted two of him for this deck. In theory, he should work as an alternative win condition, but I've only played him a few times for 9 mana, and I didn't like losing my entire deck with a bunch of Radiants and other creatures mixed in, and I even lost twice because of it. But I was also less experienced back then. However, using Acceleration to add four cards to your deck when you don't have much else to play, or post-Deus, when you have a lot of power points, are very good additional options. I've won several times with their help, although often I just ignore the cards and refresh my hand in search of Radiants. It's not always ideal, but overall, the cards in it help, and there are also two draw cards for Resonance.
