As requested on the level page.
These "older" levels are a bit challenging to provide useful strategies for, because my cards are way, way more highly-leveled than someone first encountering this level should have.
So I took two major handicaps for myself:
- I only used 6 card slots
- I did not upgrade a single tower
Please use all your card slots and/or upgrade something if you're trying to pass this level.
Here's a screenshot of what I just did for each of the last four waves to give you an idea of how your towers can be placed:
