(10/1/2007) If there are no nonland permanents on the battlefield other than an Oblivion Ring, and the card it exiled was another Oblivion Ring, casting a third Oblivion Ring will result in an involuntary infinite loop that will end the game in a draw (unless someone chooses to break it by putting another nonland permanent onto the battlefield or destroying one of the Oblivion Rings, for example)
And even once I had my job, I feel that I took an active hand to move my job toward what I wanted to do
Versus Fortress Leader Catherine, all Electric type damage is increased by 10
Mortality Spear Four mana to destroy a nonland permanent is quite expensive, but 2 is a steal
The issue with the card is that it is hard to turn back on in the late game
If you can reanimate this for cheap, then for only four black mana, you get to draw seven cards
