The basic idea of this deck is to overrun your opponent with rats. Razortooth Rats are good for dealing damage unintercepted, and Pestilence Rats can beacome a very very large rat. Dark Rituals help the game get started fast with the more exspensive rats or help you buy back more Lab Rats. Later in the game, Lab Rats become useful when you have lots of mana or if you need intercepters. Necropotence is a big help when your hand runs out. This will allow you to swarm your opponent even faster. Although Rats of Rath are said to be rather worthless, they are a good second turn creature. Don't be afraid to pump up the Sewer Rats because it will hurt you, because you need to get in every hit you can. And when you're being swarmed by your opponent or need a way to quickly finish the game, Crypt Rats are there to help.
