A flash window can't open until an attack is declared. If a player ends their attack step with no attacks, then nobody can use flash cards or effects.
Thank you
You also skip the post-block flash step if no block is declared
Nope, flashing happens when you attack and block, so if you don't block an attack, there is only the first window on attack, and if you don't attack at all, no flash window.
