Earthbend X turns a land you control into a 0/0 land creature with haste and puts X +1/+1 counters on it. If that earthbended land dies or is exiled, it returns to the battlefield tapped, making animated lands substantially less fragile than usual.
Bumi, Unleashed can create an additional combat specifically for land creatures, Ba Sing Se provides repeatable earthbending from the mana base, and Toph, the First Metalbender can make nontoken artifacts into lands that are themselves eligible to be earthbent.
