Great Post.
I am still getting to know the new cards as I have not leveled them up. I am a big fan of Doctor Blight, Mycelic Slipspawn and the Deeplurker. They work well with my current line ups. I will keep playing around with the new cards and see what works best.
Good luck with your battles.
Well. soon my wife will make a version of this post for bronze rank cards, that could help you a lot too, I also really like the Deeplurker, it may be an ugly fish but it hits hard and I like that a lot.
