I don’t mean to cause problem for the format. I just truly believe that this or any future printing that can function through the turbo mana shell is going to be a target for restriction until they correct the underlying issue.
They restricted Karn strictly based on player feedback. The “problem” with that is the players got it wrong. They were losing to Karn and thought Karn was the problem. It wasn’t. Karn was just a powerful win condition enabled by a broken mana base.
They need to start looking at the root causes of these disturbing Turbo comb0 decks and not just take the first thing that jumps out.
