1. None of them. If I had to pick one it would be Steal.
2. This (

3. Various Kongregate games and chess.
4. From the looks of it I'd say Hyroen.
5. Rain of Fire. Such an evil card, especially against Mono Darkness.
6. Probably Elements Chess.
7. Shard of Void, Parallel Universe, Shockwave, Nightmare, Soul Catcher, Earthquake, Antimatter, Phoenix, Black Hole, Druidic Staff, Crusader, Precognition, Freeze.
8. The time I removed the wrong card from the Darkness Crucible poll thread just yesterday. Imagine my embarrassment. (Don't worry, I fixed it.)
9. Besides the fact that it's a truly free game, that it's such a friendly/awesome community, and my own desire for power, nothing.
10. Just do what it's doing; it's getting bigger and better every day.
