That's not quite right sorry, Airstrip doesn't have guaranteed evo brick drops, but they are fairly common, around a 40% chance. Every run will give you four things, two from the shard/rune category which includes the bricks, and two from the currency/talisman category. The two cosmic evo materials has a small chance as an extra reward. So it's possible to get zero, one, or even two bricks each run.


If you need heaps of yellow bricks, the Labyrinth dungeon is the better option, although much more difficult.
