From what i remember you're a highly respected player for FW , so i'm going out and saying I don't understand what you're saying. With that,hoarfrost lich also has the same concern..."frost"
One of the upgrades that is automaticly taken on the Hoarfrost Dragon in the free Deck is used on an Ally ability. Since it is a FF BG is is a wasted upgrade. Not sure how i can explain it more clearly.
Now I see the lord of bones aspect as well, thank you for clarifying. It wasn't clear to me for what ever reason.
lord of bones also gives you a mysian necromancer with corrupted nora that punishes you for using the included unholy tomb
That of the highest caliber of course I've destroyed enemy shrines on their turn That might be one way to know if you've played against me.
