sure the new artilleryWhat units do you do need to defeat ?
1st wave: 1 Ronin, 1 Rocket Troop, 1 Ninja, 2 Samurai, 1 Eel, 1 Glider, 1 OF-Champion
2nd wave: 2 Rocket Troops, 1 Samurai, 2 Nautilus, 1 Eel, 2 Crab
And I tried manual battle multiple times
Edit: An attack formation with 2 Ronin, 2 Rocket and 4 Rogues did the trick.
I would negotiate it. In the VF players have plenty of goods.
