[BTD6] Tricky Tracks CHIMPS Black Border w/ Silas & Axis of Ice

one last coldchain spam run, kinda [Version 56.3] Before Coldchain is going to get heavy nerf in the future, I want to do Axis of Ice because of Silas lv13. Once again, Coldchain spam is so effective and super cheap to get, making all tier 5 ice monkey so much stronger. 0:00 early game 5:36 mid game 10:10 late game
