If you don't have the money to test, you could go to the trainer.
Now to the decks,
The first one is okay, a good mono-entropy. I can't seem to tweak it much, it's good as it is. However, you might want to add another pillar for something like a discord.
To the second one, the only way I could make it better was by either adding - 1 lycan instead of a pillar, 1 arsenic or vamp stilleto instead of hammer.
Edit : Ninja'd by willng.
