An extremely fun deck to play with, and torturous to play against. Attacking and blocking is a pain for anyone who knows this deck. It really splits up into three main parts that force your opponents to make a gamble almost every turn.
Attacking:A combination of Throat Slitter's and Ink-Eyes, Servant of Oni's ninjitsu along with Tragic Slip and Bone Picker's morbid effect. Attacking with a 1/1 death touch is hilarious as you watch your opponent struggle to figure out whether they want to lose a creature to this puny 1/1 or risk you ninjitsu-ing in a Throat Slitter or Ink-Eyes, Servant of Oni. If they do block, however, a creature did just die, so you can now have one of their poor creatures have a very Tragic Slip or simply get an amazing one mana flier with Bone Picker. Rancid Rats is an amazing ninjitsu trigger.
Blocking:Tons of death touch...what can I say? Ogre Slumlord turns any rat into your best blocker, plus makes more blockers!
Building:While your opponent is agonizing over attacking and blocking, if you don't have a really good hand you can just wait and psych your opponent out while waiting for the godly Pack Rat. This is a real powerhouse, I have gotten multiple of them to 13/13 and used them to destroy my opponent. This card turns every useless card in your hand into another pack rat, along with every card in your deck.
Removal in this deck consists of the amazing Tragic Slip which kills everything I've come across and doesn't give a rip about indestructible creatures. Murderous Compulsion isn't very good on its own, but has good synergy with Pack Rat so I run a couple. Other than that, you basically just try to build or kill your way to victory.
