It could be a nice initiative but who are you to decide what cards get banned? You simply listed all cards that you don't like being played against you and called it a day. There is no deep thought behind it, what does it work on? The most played cards in the top archetypes? The cards that you think would ruin the archetypes?

First of all, your bans do not touch the highest winrate deck in the game, Secret Libram Paladin. They do not run Conviction. Additionally, you put Tickatus there, as part of a tier 4 deck in a class that struggles to see success in the meta. While Secret Passage is a huge contributor to Rogue's success, they have so many ways to draw cards that they will probably not be too affected. Also, while some of these bans hurt, but do not kill the decks (Imprisoned Felmaw, Athletic Studies), others are completely obliterated (Arbor Up, Skull of Gul'dan, Incanter's Flow).

So people will just play the least impacted meta decks, something like Libram Paladin, Tempo/Secret Rogue and Rush Warrior or Guardian Animals Druid. Additionally, many decks have ways to discover and generate the banned cards. How does the ban work then? Are you going to punish players for getting secret passage off wandmaker? Or Arbor up from Nature Studies.

As I said, there is a lot of potential for this idea. Maybe try to look again at what cards create archetypes in the first few tiers and remove 3 cards from each class and up to 10 from neutral, make people fall in love with deckbuilding again. Maybe stream it too. Although, for all of that effort, you probably need a prize of some sorts to create enough hype and fill in the 32 slots.

Good luck!
