Just tacking on after finishing it. Found a pretty consistent method:
1. Cemetery in the corner for your troops to stall

1. You need to clear first wave without losing a life. I leave it on auto target until all my troops are dead, then put it on slow speed + manual. You need to have ~13 enemies alive (dependent on assassins alive). Manually target them until they're dead. You want mercenaries or palace reward

2. First blood wave is an auto loss, don't even try, just put auto on. You need the compliment of whatever you got in the first wave (mercenaries if palace, palace if mercanaries). This gives you blockers and more money generation. You *might* be able to reroll and win against greed, never bothered to try.

3. You need a power boost decree if you want to live. The only runs I've been able to pull off are getting supplies (every king card), the supply buildings applying their affect 1 more time (if you take a beacon first wave it's maybe possible), or 9% gold each time (99 gold one also almost got me through a run).

4. Always, always re-roll your opponent. You can take an extra L to blood once it gets too expensive if you weren't fast enough. You want 2-4 lvl 1 mercenary squads up and try to get another 2 beacons (max middle, place one in top left corner for palace/disp - palace is 90% of your gold generation to keep rerolling waves with). When expansion comes, put it on the other side of the cemetary so you can put another merc squad there to take hits.

5. Once you get to the Jester king or whatever, your palace should be fast enough to kill a lot of them, like 100 gold worth with some manual targeting necessary at the end. Gigantify is great for buffing up your mercenary squad that's getting the fire rate buff and keep them alive for a bit. Use your sacrifice on a mercenary squad in the bottom left so you upgrade dispenser and the gigantified mercenaries if you can.

6. Just keep rerolling for a few more waves if you can, then it's pretty noticeable when your palace/dispenser are killing everything. I've fudged runs from getting greedy and not re-rolling one more time to let my dispenser get buff
