Ancient Cheetah Smoke from T Spawn
TechniqueJumpthrow + W
Position yourself in the corner next to the rock and aim as shown (align vertically at the top of the single leaf, horizontally with the arrow created by the building and treeline below). Move forward until your crosshair is roughly on the aforementioned arrow. Hold shift, tap W and jumpthrow (or use a jumpthrow+forward keybind). This lineup is 100% consistent.
On 64-tick, aim slightly higher.
