Oh, where were we? Um, yes, 4, the answer is four.

EDIT: Except for the basic lands, you can have any number of basic lands in your deck. The name of the basic lands are Plains, Island, Swamp, Mountain, and Forest.

4 is the standard, but you can have as many relentless rats in your deck as you want!

There are eleven cards that can break that limit. Six have already been named (the basic lands, and Relentless Rats). The other five are the snow-covered basic lands.
