Type 2 Budget Skull Collector Rats (no Rares)
This deck can be a control deck or a beatdown deck. The deck stabilizes early in the game with Bile Urchin and disruption in the form of Ravenous Rats and Chittering Rats. The deck then gets a lock on the opponents hand by using Skull Collector to repeatedly bounce a Ravenous Rats, or a Chittering Rats to back to their hand, then replays the creature. Ravenous Rats makes them discard whatever they have in their hand, and Chittering Rats makes it so they cannot draw anything more. Obika-Gang Shinobi can also do this job very well. Nekrataal and Throat Slitter are here to take care of whatever the opponent manages to slip past your hand disruption. If you aren't beating your opponent down, you can win by repeatedly bouncing a Highway Robber back to your hand and replaying it. Nezumi Graverobber wrecks reanimator decks, plus it can bring back whatever you get rid of with the Rats, Nekrataal, and Throat Slitter. It even has an added bonus of having a little combo with Bile Urchin. Finally, Quicksand is some extra removal that is not out of the way to have (since it is a land) so it works well. I have not made a sideboard for this deck; I suggest just looking for answers to whatever problems you come across in gameplay. Have fun with this deck!
