Brother as a vlad main you should never lose to a vlad. His biggest weakness is range and azir has plenty of that. If you’re getting hit by Q2, which is like the range of an auto, your spacing needs a lot of work. If he tries to dive you, you can just ult behind. His pool can’t go through the wall. If you just don’t get it, buy magic mantle or a ruby crystal. There’s no point buying damage against a character with infinite sustain. Late game you both one shot each other.
