Azorius Standstill plays a taxing control game with Counterspell, Mana Leak, and Prohibit backed by Standstill to deny you card development — breaking Standstill gives them three free cards, but not breaking it means you can't develop your combo. The key interaction to respect is that they run Disenchant effects for your Lotus Petals and a clean answer suite for most threats; you need to time your combo turn carefully and use Orim's Chant to buy the window to resolve Brain Freeze uncountered. Divert is excellent for redirecting Counterspell or Mana Leak back at their own permission spells, effectively giving you a free counter. Humility is largely irrelevant against you since you're not a creature deck, but Standstill slows your setup considerably — consider breaking it deliberately on your own terms when you're ready to combo rather than letting them dictate the pace. Their Annul in the board hits your Lotus Petal and Gemstone Mine, so be aware of artifact-heavy lines post-board.
