Snakes are a creature type appearing predominantly in green, with support ranging from typal combat to deathtouch, tokens, card draw, and +1/+1 counters. Kamigawa's Orochi provide much of the traditional kindred backbone.
Sosuke, Son of Seshiro rewards Snake combat, while Hooded Hydra can leave a pile of Snake tokens behind when it dies. Xyris takes the tribe in an entirely different direction by turning opponents' extra card draws into Snakes.
