A mono-black rat tribal deck that utilizes ninjutsu.
Karumonix, the Rat King wishes to be frequently cast mainly for its third ability to keep our hand filled with rats. Ogre Slumlord gives all our Rats deathtouch and can create Rat 1/1 B Tokens whenever a nontoken creature dies to make us profit off of boardwipes.
Piper of the Swarm makes all our Rats and Rat 1/1 B Tokens have menace which will aid in getting our strong ninja rats out. Silver-Fur Master will reduce the cost of our Ninjutsu abilities, and all Ninjas and Rogues will get +1/+1 for each Silver-Fur Master on the field, which will affect Ink-Eyes, Servant of Oni, Nashi, Moon Sage's Scion, Nezumi Prowler, Silver-Fur Master, and Ogre Slumlord. Ornithopter can attack for zero flying damage to easily ninjutsu, and then replay the Ornithoper immediately
Nashi, Moon Sage's Scion can steal cards from the top of libraries which is especially useful in multiplayer games and Ink-Eyes, Servant of Oni is a strong ninjutsu rat that can regenerate and steal creatures from opponent's graveyards.
Pack Rat grows bigger from all of our rats and can make duplicates of itself by discarding unwanted cards. Nezumi Prowler synergizes well with Pack Rat by suddenly giving it deathtouch and lifelink. Pack Rat is optimally played on turn 5 to create a copy of itself on the same turn. Unearth and Witch's Cottage can be used to keep Pack Rat a constant board presence as well as bringing almost any creature discarded by Pack Rat back into our library or straight onto the battlefield in Unearth's case.
