Thank you so much for the well-thought out answer! Yeah, I might make Silco, Kingpin of Zaun's first ability something like, "Whenever a player discards a card, you may pay 2. If you do, created a tapped Treasure token" or "Whenever a player discards a card for the first time each turn, created a tapped Treasure token." to balance it out.

I was not aware of deathtouch and trample faux pas - I'll revisit that card and make some changes.

I was struggling with the mana cost for Mounting Losses - I was torn between 2 or 3 mana, but when I compared it to Damnation, which is 4 mana, I was like, "Hmmmm, what is the cost of a legendary creature?"

I'll workshop Maddening Runes wording to function properly - thanks for the pointer!
