"Games with Krark-Clan Ironworks can often involve excessively arcane rules interactions using mana ability timing windows, the understanding of which are necessary for players to agree on the game state. This can create a barrier to entry to Modern for players playing against the deck and to those who would feel obligated to play with it because of its strong win rate."
@DialMforMara I'm glad they didn't ban Ancient Stirrings. I think people comparing it to Ponder & Preordain are just wrong. Ancient Stirrings has deckbuilding constraints, no matter how trivial, whereas P&P just require you to have blue mana sources.
Banning Ironworks itself shows that WotC really does not want >10 minutes of nondeterministic looping to be the future of modern.
