Icebox

Use this aggressive teleport at the start of the round to peek enemies at Mid from ontop of Tube. Combine this with a falling smoke before teleporting so the enemies cannot see the teleport animation

Aim the smoke at the path left of Tube and move it up until the center is next to the top of Tube and use it immediately. Then wait a second for the smoke to pop and jump off the Kitchen step to teleport ontop of Tube
