Story about The Abyss.
A while back, a friend cast The Abyss on turn 2 or 3. By turn 5, he was complaining about it effectively preventing him from casting his Commander. He would not stop asking the the rest of the table to destroy it for him.
Eventually I gave in, cast Demonic Tutor, and removed his Abyss... by playing The Abyss.
Another game, an opponent was playing Elves, and had been hamstrung by my Abyss. Eventually, he drew into Naturalize (or equivalent), and destroyed it. That same turn, he then played a Concordant Crossroads. I think he had it in hand for several turns.
