How play Indians in 1vs1

Indians are real good civs in team game, but I don't know how play them in 1vs1.

​

They don't have knight line, and they don't have eagles, yes they are not meso.

They don't have arb. not full up infantry, don't have siege ram, siege ornager.

​

So I feel confuse, what to do. UUs are expensive, so hard to use in 1vs1.

What is best play when they don't need camels? For example vs meso or archer civs.
