[HoMM V]9 Race - Swamp! Is it needed?

These are just options. And Leтунчик, what don't you like about the snake? I mean, without the lizard rider, like in the third game. One unit, flies fast.
P.S. No matter how enthusiastic you are, you can't create a new race on your own. You need to think about a team, and a big one. This is just advice. ;)
