Denshikova's Efficiency Challenge but with Difficulty 4? Can we do it? lol.

Efficiency Challenge Rules: • Start with any commander (Your preference, I prefer Denshikova). • Pick your first two towers; you can't place any other tower that has its own efficiency or cost reduction doctrines until you have first cleared both cost reduction 3, and efficiency 3 for one of your current towers. • As you clear a tower fully (Expertise is a bonus, not required btw) you may then select your next tower to replace the one you just finished. • Any tower that does not have its own cost reduction or efficiency doctrines may be placed at any time (Ammo Depots, Fortress, etc). • All towers you have already cleared fully may be placed at any time after clearing them as well. • You may only earn new towers as you clear the current 1-2 you're working on. You do not have to clear both to unlock 2, you can unlock 1, as 1 is cleared in rotation. • You may choose tile placement of your preference (Spiral, Zig Zag, etc). • This challenge relies on a mix of RNG and clever planning on your tile placements, and the use of new towers based on what the current run is throwing at you.
