I made an Arena BO for a Cuman Ram Trush into Boom:
It’s an advanced BO, you have to start pushing your deer early otherwise you won’t have enough food to click up immediately, after garrisoning your vills at the end of loom.
As you will see, it puts nothing less than 6 on Wood initially + 3 more after clicking up to feudal. So no wonder your initial attempt didn’t had enough wood. Even this buildorder will only allow you to make like 3 rams or so.
The idea of the build is to distract the opponent so much that he can’t really threaten your cuman boom. But you need to be very careful with your forward vills and rams.
Feudal Rams are not only expensive for that stage but also take a long time cause you need to make 2 buildings before you actually get them out. That’s why I combine it with a trush, as the trush hits already earlier and forces a reaction. Usually a reaction that actually plays into your cards with the ram followup.
