When I declare multiple attackers, do they deal damage at the same time, or do they attack sequentially?
For an example, I attack with Aethergeode Miner and Ninth Bridge Patrol. If they attack simultaneously, I've got a 3/1 and a 1/1. If they attack sequentially, I could use the Miner first, flicker it, and then I'd have a 3/1 and a 2/2, since the Patrol gains +1/+1 for each creature that flickers.
Do attacking creatures work simultaneously?
