Thanks, appreciate the feedback as it's hard to come by. There are times were I'm like "is my content just garbage" when it doesn't do well so nice to know I have at least a couple fans lol.
I'm still gathering experience with the silver leader board myself, this will be my first season really trying for it so I'll have to see what works and what doesn't. Once I actually hit it, I'll definitely do a guide, as I was already thinking about it.
One thing that really surprised me so far just to give a taste is Uriel The Purifier at level 2 (silver max) is way better than I thought. A lot of people hate recharge, myself included, but he has overperformed for me as a tank with the self heal. Toss in Adelade for repair and CrystalSmith for a second heal and he's very durable against anything but the heaviest magic spam.
He's a card I'll be trying to buy more copies of as I think he'll also work well with the new legendary summoner. (compared to general sloan who does nothing for him)
