For India there is a mango grove card, if you can send 2 of them on Industrial and resend them again on imperial there is a potential of 30k wood and the only wood India use in late game only for Mahout and Siege Elephant.
For the native the problem isn’t that big for Inca that got moon ceremony and Lakota as Wakina, AR, RR are not using wood, the only wood lakota would use for late game are only for imperial upgrade and to some extend club warrior. But the problem is bigger when playing Hauds and Aztec as their crucial unit are costing wood, the Tomahawk for Hauds and Coyote for Aztec.
