The Battle Cats - Black Summit, Summit Shrine (Merciless)
The main difficulty here is the lack of money. Using a rich cat is an easy solution, though 1. it's not required and 2. this is a farming stage, so I opted for worker combos instead.
The best thing you can do here is be efficient with your spawns. Don't summon extra units unless you have to, and use your cannon wisely to keep those you've already deployed alive for as long as possible.
Your main goal here is freezing Le'noir: once that happens, you pretty much win.
"What if I don't have pizza" then I guess you're screwed, and you have to put off beating this :v
